rtnetlink: remove redundant checks for nlattr IFLA_BRIDGE_MODE The commit d73ef2d69c0d ("rtnetlink: let rtnl_bridge_setlink checks IFLA_BRIDGE_MODE length") added the nla_len check in rtnl_bridge_setlink, which is the only caller for ndo_bridge_setlink handlers defined in low-level driver codes. Hence, this patch cleanups the redundant checks in each ndo_bridge_setlink handler function.

Introduce skb_frag_fill_page_desc() to do that. net/bpf/test_run.c does not call skb_frag_off_set() to set the offset, "copy_from_user(page_address(page), ...)" and 'shinfo' being part of the 'data' kzalloced in bpf_test_init() suggest that it is assuming offset to be initialized as zero, so call skb_frag_fill_page_desc() with offset being zero for this case.

be2net: Drop redundant pci_enable_pcie_error_reporting() pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

be2net: Use irq_update_affinity_hint() The driver uses irq_set_affinity_hint() to update the affinity_hint mask that is consumed by the userspace to distribute the interrupts. However, under the hood irq_set_affinity_hint() also applies the provided cpumask (if not NULL) as the affinity for the given interrupt which is an undocumented side effect. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Hence, replace the irq_set_affinity_hint() with the new interface irq_update_affinity_hint() that only updates the affinity_hint pointer.

So, if it fails, the 32 bits case will also fail for the same reason. So if dma_set_mask_and_coherent() succeeds, 'netdev->features' will have NETIF_F_HIGHDMA in all cases.

ethernet: constify references to netdev->dev_addr in drivers This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

be2net: convert to new udp_tunnel_nic infra Convert be2net to new udp_tunnel_nic infra. NIC only takes one VxLAN port. Remove the port tracking using a list. The warning in be_work_del_vxlan_port() looked suspicious - like the driver expected ports to be removed in order of addition. be2net unregisters ports when going down and re-registers them (for skyhawk) when coming up, but it never checks if the device is up in the add_port / del_port callbacks. Make it use UDP_TUNNEL_NIC_INFO_OPEN_ONLY. Sadly this driver calls its own open/close functions directly so the udp_tunnel_nic_reset_ntf() workaround is needed.

net: move skb->xmit_more hint to softnet data There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

be2net: don't flip hw_features when VXLANs are added/deleted the be2net implementation of .ndo_tunnel_{add,del}() changes the value of NETIF_F_GSO_UDP_TUNNEL bit in 'features' and 'hw_features', but it forgets to call netdev_features_change(). Moreover, ethtool setting for that bit can potentially be reverted after a tunnel is added or removed. GSO already does software segmentation when 'hw_enc_features' is 0, even if VXLAN offload is turned on. In addition, commit 096de2f83ebc ("benet: stricter vxlan offloading check in be_features_check") avoids hardware segmentation of non-VXLAN tunneled packets, or VXLAN packets having wrong destination port. So, it's safe to avoid flipping the above feature on addition/deletion of VXLAN tunnels.

Lancer firmware goes into an error state and indicates this back to the driver via a bit in a doorbell register. b) Driver detects this and calls be_err_recover(). DMA is disabled, all pending TX skbs are unmapped and freed (be_close()). All rings are destroyed (be_clear()). c) The driver waits for the FW to re-initialize and re-creates all rings along with other data structs (be_resume()) Signed-off-by: Suresh Reddy <suresh.reddy@broadcom.com> Signed-off-by: David S.

This causes a regression because potential promiscuous mode is not restored properly during be_open() because the driver thinks that the HW has promiscuous mode already enabled.

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE() Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Paul E.

be2net: fix initial MAC setting Recent commit 34393529163a ("be2net: fix MAC addr setting on privileged BE3 VFs") allows privileged BE3 VFs to set its MAC address during initialization. Although the initial MAC for such VFs is already programmed by parent PF the subsequent setting performed by VF is OK, but in certain cases (after fresh boot) this command in VF can fail. The MAC should be initialized only when: 1) no MAC is programmed (always except BE3 VFs during first init) 2) programmed MAC is different from requested (e.g. MAC is set when interface is down). In this case the initial MAC programmed by PF needs to be deleted.

be2net: fix MAC addr setting on privileged BE3 VFs During interface opening MAC address stored in netdev->dev_addr is programmed in the HW with exception of BE3 VFs where the initial MAC is programmed by parent PF. This is OK when MAC address is not changed when an interfaces is down. In this case the requested MAC is stored to netdev->dev_addr and later is stored into HW during opening. But this is not done for all BE3 VFs so the NIC HW does not know anything about this change and all traffic is filtered. This is the case of bonding if fail_over_mac == 0 where the MACs of the slaves are changed while they are down. The be2net behavior is too restrictive because if a BE3 VF has the FILTMGMT privilege then it is able to modify its MAC without any restriction. To solve the described problem the driver should take care about these privileged BE3 VFs so the MAC is programmed during opening. And by contrast unpriviled BE3 VFs should not be allowed to change its MAC in any case.

benet: stricter vxlan offloading check in be_features_check When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured.

net: Update API for VF vlan protocol 802.1ad support Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

be2net: Support UE recovery in BEx/Skyhawk adapters This patch supports recovery from UEs caused due to Transient Parity Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids system reboot when such errors occur. The driver recovers from these errors such that the adapter resumes full operational status as prior to the UE. Following is the list of changes in the driver to support this: o The driver registers its UE recoverable capability with ARM FW at init time. This also allows the driver to know if the feature is supported in the FW. o As the UE recovery requires precise time bound processing, the driver creates its own error recovery work queue with a single worker thread (per module, shared across functions). o Each function runs an error detection task at an interval of 1 second as required by the FW. The error detection logic already exists for BEx/SH, but it now runs in the context of a separate worker thread. o When an error is detected by the task, if it is recoverable, the PF0 driver instance initiates a soft reset, while other PF driver instances wait for the reset to complete and the chip to become ready. Once the chip is ready, all driver instances including PF0, resume to reinitialize the respective functions. o The PF0 driver checks for some recovery criteria, to determine if the recovery can be initiated. If the criteria is not met, the PF0 driver does not initiate a soft reset, it retains the existing behavior to stop further processing and requires a reboot to get the chip to operational state again. o To allow each function to share the workq, while also making progress in its recovery process, a per-function recovery state machine is used. The per-function tasks avoid blocking operations like msleep() while in this state machine (until reinit state) and instead reschedule for the required delay. o With these changes, the existing error recovery code for Lancer also runs in the context of the new worker thread.

be2net: replace polling with sleeping in the FW completion path The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with BHs disabled. The driver currently issues the required cmds to the FW in these contexts and polls on completions from the FW, while BHs remain disabled. This can cause either packet loss or packet reception to be delayed on that CPU. This patch defers processing of the above cmds to a separate workqueue. With this change, FW cmds are now issued only in process context. Now that the FW cmds are issued only in process context, they can sleep waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock) calls are now replaced with mutex calls. Also a new rx_filter_lock is now needed to protect the RX filtering fields like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

This leads to a flood of RX_FILTER cmds when a number of vlan interfaces are configured over the device, as the ndo_ gets called for each vlan interface. To avoid this, we now use __dev_mc_sync() and __dev_uc_sync() API, but only to detect if there is a change in the mc/uc lists. Now that we use this API, the code has to be-designed to issue these API calls for each invocation of the be_set_rx_mode() call.

Nevertheless, this fw temperature query is invoked only for adapters which interface is up, so we can see I/O errors on read of hwmon counters from userspace (from tools like lm-sensors) in case we have adapters' functions which interface is down.

be2net: Fix broadcast echoes from EVB in BE3 On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3 vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes broadcast and multicast packets back to PF's vport confusing the Linux bridge. BE3 relies on the src-mac addr being programmed on the interface to avoid sending back an echo of a broadcast or multicast packet on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the VM behind the bridge doesn't get configured on the vPort and so echo cancellation doesn't work. This patch worksaround this problem by disabling the EVB initially and re-enabling it *only* when SR-IOV is enabled by the user. For the driver fix to work, the BE3 FW version must be >= 11.1.84.0.

be2net: support asymmetric rx/tx queue counts be2net so far supported creation of RX/TX queues only in pairs. On configs where rx and tx queue counts are different, creation of only the lesser number of queues has been supported. This patch now allows a combination of RX/TX-only channels along with combined channels. N TX-queues and M RX-queues can be created with the following cmds: ethtool -L ethX combined N rx M-N (when N < M) ethtool -L ethX combined M tx N-M (when M < N) Setting both RX-only and TX-only channels is still not supported. It is mandatory to create atleast one combined channel. Signed-off-by: Sathya Perla <sathya.perla@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

be2net: fix definition of be_max_eqs() The EQs available on a function are shared between NIC and RoCE. The be_max_eqs() macro was so far being used to refer to the max number of EQs available for NIC. This has caused some confusion in the code. To fix this confusion this patch introduces a new macro called be_max_nic_eqs() to refer to the max number of EQs avialable for NIC only and renames be_max_eqs() to be_max_func_eqs().

be2net: Fix provisioning of RSS for VFs in multi-partition configurations Currently, we do not distribute queue resources to enable RSS for VFs in multi-channel/partition configurations. Fix this by having each PF(SRIOV capable) calculate it's share of the 15 RSS Policy Tables available per port before provisioning resources for all the VFs. This proportional share calculation is done based on division of the PF's MAX VFs with the Total MAX VFs on that port. It also needs to learn about the no: of NIC PFs on the port and subtract that from the 15 RSS Policy Tables on the port.

be2net: Enable Wake-On-LAN from shutdown for Skyhawk Skyhawk does support wake-up from ACPI shutdown state - S5, provided the platform supports it (like Auxiliary power source etc). The changes listed below are done to fix this. 1) There's no need to defer the HW configuration of WOL to be_suspend(). Remove this in be_suspend() and move it to be_set_wol() ethtool function so it is configured directly in the context of ethtool. This automatically takes care of the shutdown case. 2) The driver incorrectly uses WOL_CAP field in the FW response to get_acpi_wol_cap() command, to determine if WOL is enabled. Instead the driver must rely on the macaddr field in the response to infer WOL state. 3) In be_get_config() during init, if we find that WOL is enabled in FW, call pci_enable_wake() to enable pmcsr.pme_en bit. This is needed to support persistent WOL configuration provided by the FW in some platforms. 4) Remove code in be_set_wol() that writes to PCICFG_PM_CONTROL_OFFSET to set pme_en bit; pci_enable_wake() sets that.

be2net: use max-TXQs limit too while provisioning VF queue pairs When the PF driver provisions resources for VFs, it currently only looks at max RSS queues available to calculate the number of VF queue pairs. This logic breaks when there are less number of TX-queues than RSS-queues. This patch fixes this problem by using the max-TXQs available in the PF-pool in the calculations. As a part of this change the be_calculate_vf_qs() routine is renamed as be_calculate_vf_res() and the code that calculates limits on other related resources is moved here to contain all resource calculation code inside one routine.

be2net: don't enable multicast flag in be_enable_if_filters() routine When the interface is opened (in be_open()) the routine be_enable_if_filters() must be called to switch on the basic filtering capabilities of an interface that are not changed at run-time. These include the flags UNTAGGED, BROADCAST and PASS_L3L4_ERRORS. Other flags such as MULTICAST and PROMISC must be enabled later by be_set_rx_mode() based on the state in the netdev/adapter struct. be_enable_if_filters() routine is wrongly trying to enable MULTICAST flag without checking the current adapter state. This can cause the RX_FILTER cmds to the FW to fail. This patch fixes this problem by only enabling the basic filtering flags in be_enable_if_filters(). The VF must be able to issue RX_FILTER cmd with any filter flag, as long as the PF allowed those flags (if_cap_flags) in the iface it provisioned for the VF. This rule is applicable even when the VF doesn't have the FILTMGMT privilege. There is a bug in BE3 FW that wrongly fails RX_FILTER multicast programming cmds on VFs that don't have FILTMGMT privilege. This patch also helps in insulating the VF driver from be_open failures due to the FW bug.

This is because when the TXULP pulls the TX WRB to check the length of the frame to be transmitted it also adds the size of VLANs to be inserted by the HW to the length of the frame indicated in the WRB, which in some cases fails the range check.

be2net: set pci_func_num while issuing GET_PROFILE_CONFIG cmd The FW requires the pf_num field in the cmd hdr to be set for it to return the specific function's descriptors in the GET_PROFILE_CONFIG cmd. If not set, the FW returns the descriptors of all the functions on the device. If the first descriptor is not what is being queried for, the driver will read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG cmd.

be2net: fix BE3-R FW download compatibility check In the BE3 FW image, unlike Skyhawk's, the "asic_type_rev" field doesn't track the asic_rev of chip it is compatible with. When asic_type_rev is 0 the image is compatible only with pre-BE3-R chips (asic_rev < 0x10). Fix the current compatibility check to take care of this.

be2net: avoid vxlan offloading on multichannel configs VxLAN offloading is not functional if the NIC is running in multichannel mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole connectivity through the NIC and the device needs to be down and up to restore it. The firmware should take care about it and does not allow the conversion of interface to tunnel type (be_cmd_manage_iface) or should support VxLAN offloading if multichannel config is enabled. I have tested this on the latest available firmware (10.6.144.21).

Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg. Before this patch, "bridge vlan show": $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlans 57 sw1p1 << device side vlans (missing) sw1p2 57 sw1p2 sw1p3 sw1p4 br0 None (When the port is bridged, the output repeats the vlan list for the vlans on the bridge side of the port and the vlans on the device side of the port. The listing above show no vlans for the device side even though they are installed). After this patch: $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlan 57 sw1p1 30-34 << device side vlans 57 3840 PVID sw1p2 57 sw1p2 57 3840 PVID sw1p3 3842 PVID sw1p4 3843 PVID br0 None I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func. switchdev support adds an obj dump for VLAN objects, using the same call-back scheme as FDB dump.

cpumask_set_cpu_local_first => cpumask_local_spread, lament da91309e0a7e (cpumask: Utility function to set n'th cpu...) created a genuinely weird function. I never saw it before, it went through DaveM. (He only does this to make us other maintainers feel better about our own mistakes.) cpumask_set_cpu_local_first's purpose is say "I need to spread things across N online cpus, choose the ones on this numa node first"; you call it in a loop. It can fail. One of the two callers ignores this, the other aborts and fails the device open. It can fail in two ways: allocating the off-stack cpumask, or through a convoluted codepath which AFAICT can only occur if cpu_online_mask changes. Which shouldn't happen, because if cpu_online_mask can change while you call this, it could return a now-offline cpu anyway. It contains a nonsensical test "!cpumask_of_node(numa_node)". This was drawn to my attention by Geert, who said this causes a warning on Sparc. It sets a single bit in a cpumask instead of returning a cpu number, because that's what the callers want. It could be made more efficient by passing the previous cpu rather than an index, but that would be more invasive to the callers.

be2net: Support for OS2BMC. OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.

be2net: add support for spoofchk setting This patch adds support for spoofchk configuration for VFs. When it is enabled, "spoof checking" is done for both MAC-address and VLAN. For each VF, the HW ensures that the source MAC address (or vlan) of every outgoing packet exists in the MAC-list (or vlan-list) configured for RX filtering for that VF. If not, the packet is dropped and an error is reported to the driver in the TX completion; this is reflected in the "tx_spoof_check_err" ethtool counter. This feature is supported in Skyhawk FW version 10.6.31.0 and above.

This condition is more reliably detected (i.e., returns all ones) with an MMIO read rather than a config read -- especially on power platforms. Hence, this patch fixes EEH error detection by replacing config reads with MMIO reads for reading the error registers.

Recent FWs (10.2 and above) support a scheme of FW-update wherein the "offset" of the component in the flash area can be specified instead of the "type".

be2net: support TX batching using skb->xmit_more flag This patch uses skb->xmit_more flag to batch TX requests. TX is flushed either when xmit_more is false or there is no more space in the TXQ. Skyhawk-R and BEx chips require an even number of wrbs to be posted. So, when a batch of TX requests is accumulated, the last header wrb may need to be fixed with an extra dummy wrb. This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue() and be_xmit_flush() calls. The Tx completion code is also updated to be able to unmap/free a batch of skbs rather than a single skb. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

net: Generalize ndo_gso_check to ndo_features_check GSO isn't the only offload feature with restrictions that potentially can't be expressed with the current features mechanism. Checksum is another although it's a general issue that could in theory apply to anything. Even if it may be possible to implement these restrictions in other ways, it can result in duplicate code or inefficient per-packet behavior. This generalizes ndo_gso_check so that drivers can remove any features that don't make sense for a given packet, similar to netif_skb_features(). It also converts existing driver restrictions to the new format, completing the work that was done to support tunnel protocols since the issues apply to checksums as well. By actually removing features from the set that are used to do offloading, it solves another problem with the existing interface. In these cases, GSO would run with the original set of features and not do anything because it appears that segmentation is not required.

be2net: Export tunnel offloads only when a VxLAN tunnel is created The encapsulated offload flags shouldn't be unconditionally exported to the stack. The stack expects offloading to work across all tunnel types when those flags are set. This would break other tunnels (like GRE) since be2net currently supports tunnel offload for VxLAN only. Also, with VxLANs Skyhawk-R can offload only 1 UDP dport. If more than 1 UDP port is added, we should disable offloads in that case too.

When the size of the packet received is larger than a fragment size (2K), more than one fragment is consumed for each packet. As the driver currently posts a max of 64 fragments, all the consumed fragments may not be replenished. This can cause avoidable drops in RX path.

be2net: reduce arguments passed to FW-cmd routines A pointer to adapter struct is passed anyway to all of the FW-cmd routines in be_cmds.c. For routines which query data from FW, the adapter pointer is enough to return the queried fields. There is no need to separately pass pointers to individual members of the adapter structure. This patch fixes this for be_cmd_get_fw_ver() and be_cmd_get_fw_cfg() routines.

be2net: create optimal number of queues on SR-IOV config If SR-IOV is enabled in the adapter, the FW distributes queue resources evenly across the PF and it's VFs. If the user is not interested in enabling VFs, the queues set aside for VFs are wasted. This patch adds support for the PF driver to re-configure the resource distribution in FW based on the number of VFs enabled by the user. This also allows for supporting RSS queues on VFs, when less number of VFs are enabled per PF. When maximum number of VFs are enabled, each VF typically gets only one RXQ.

be2net: fix qnq mode detection on VFs The driver (on PF or VF) needs to detect if the function is in qnq mode for a HW hack in be_rx_compl_get() to work. The driver queries this information using the GET_PROFILE_CONFIG cmd (since the commit below can caused this regression.) But this cmd is not available on VFs and so the VFs fail to detect qnq mode. This causes vlan traffic to not work. The fix is to use the the adapter->function_mode value queried via QUERY_FIRMWARE_CONFIG cmd on both PFs and VFs to detect the qnq mode. Also QNQ_MODE was incorrectly named FLEX10_MODE; correcting that too as the fix reads much better with the name change.

be2net: re-factor MCCQ error status handling code This patch improves MCCQ error status handling in the following ways: a) A MCC cmd completion returns a base-status and an addl-status. So far, the routine be_mcc_compl_process() returned only the "status" value. Now, embedd both statuses in the return value and let the caller routine access the value of interest using base_status() and addl_status() macros. b) Rename variables accordingly (base/addl) to avoid confusion while error checking. b) Some of the errors returned by FW are harmless and so an error msg is not logged for such errors. Capture this logic in a separate routine to make the code more readable.

net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate through ip tool. o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: David S.

This timeout value was roughly calculated based on 10G transmission speeds and the TX queue depth. This timeout may not be enough when the link is operating at lower speeds or in multi-channel/SR-IOV configs with TX-rate limiting setting. It is hard to calculate a "proper timeout value" that works in all configurations. This patch solves this problem by continuing to reap TX completions till the HW is completely silent for a period of 10ms or a HW error is detected. v2: implements the new scheme (as suggested by David Laight) instead of just waiting longer than 200ms for reaping all completions.

The page is un-mapped only when DMA finishes on the last frag of the page. (Thanks Ben H. for suggesting the dma_sync API!) This patch also renames the "last_page_user" field of be_rx_page_info{} struct to "last_frag" to improve readability of the fixed code.

net: Explicitly initialize u64_stats_sync structures for lockdep In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement.

be2net: fix adaptive interrupt coalescing The current EQ delay calculation for AIC is based only on RX packet rate. This fails to be effective when there's only TX and no RX. This patch inclues: - Calculating EQ-delay based on both RX and TX pps. - Modifying EQ-delay of all EQs via one cmd, instead of issuing a separate cmd for each EQ. - A new structure to store interrupt coalescing parameters, in a separate cache-line from the EQ-obj.

be2net: enable IOMMU pass through for be2net This patch sets the coherent DMA mask to 64-bit after the be2net driver has been acknowledged that the system is 64-bit DMA capable. The coherent DMA mask is examined by the Intel IOMMU driver to determine whether to allow pass through context mapping for all devices. With this patch, the be2net driver combined with be2net compatible hardware provides comparable performance to the case where vt-d is disabled. The main use-case for this change is to decrease the time necessary to copy virtual machine memory during KVM live migration instantiations. This patch was tested on a system that enables the IOMMU in non-coherent mode. Two DMA remapper issues were encountered in the previous version and both patches have been committed. commit ea2447f700cab264019b52e2b417d689e052dcfd commit 2e12bc29fc5a12242d68e11875db3dd58efad9ff Signed-off-by: Craig Hada <craig.hada@hp.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

be2net: fix unconditionally returning IRQ_HANDLED in INTx commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx() to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel from detecting interrupt storms due to broken HW. The BE2/Lancer HW issues are: 1) In Lancer, there is no means for the driver to detect if the interrupt belonged to device, other than counting and notifying events. 2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler to be called multiple times till the de-assert happens. 3) In BE2, we see an occasional interrupt even when EQs are unarmed. Issue (1) can cause the notified events to be orphaned, if NAPI was already running. This patch fixes this issue by scheduling NAPI only if it is not scheduled already. Doing this also takes care of possible events_get() race that may be caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first time zero events are detected.

be2net: fix wrong frag_idx reported by RX CQ The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.

Doing this insulates the driver from a FW bug wherin multi-channel config is wrongly reported even when not enabled.

be2net: do not modify PCI MaxReadReq size Setting the PCI MRRS to a value of 4096 (overriding the system decided value) had provided perf improvement in TX. But, IBM has provided feedback that on POWER platforms, this value is set by the system firmware, and drivers modifying this value can cause unpredictable results (like EEH errors.) So, backing off this change. On POWER7 platforms most slots, it seems, do get a MRRS of 4096. This patch reverts the following commit: "be2net: Modified PCI MaxReadReq size to 4096 bytes" commit 5a56eb10babbcd7b3796dc3c28c271260aa3608d.

be2net: event queue re-design v2: Fixed up the bad typecasting pointed out by David... In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue is serviced by a separate EQ. This is being changed as follows: - Upto 8 EQs will be used (based on the availabilty of msix vectors). Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and MCC queue are handled by the last EQ. - On cards which provide support, upto 8 RSS rings will be used, instead of the current limit of 4. The new design allows spreading the TX multi-queue completion processing across multiple CPUs unlike the previous design. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

The newly flashed version runs only after a system reset. Signed-off-by: Suresh Reddy <Suresh.Reddy@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

be2net: fix erx->rx_drops_no_frags wrap around The rx_drops_no_frags HW counter for RSS rings is 16bits in HW and can wraparound often. Maintain a 32-bit accumulator in the driver to prevent frequent wraparound. Also, incorporated Eric's feedback to use ACCESS_ONCE() for the accumulator write.

be2net: Fix race in posting rx buffers. There is a possibility of be_post_rx_frags() being called simultaneously from both be_worker() (when rx_post_starved) and be_poll_rx() (when rxq->used is 0). This can be avoided by posting rx buffers only when some completions have been reaped. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
