net/mlx4: Add VF vlan protocol 802.1ad support Move the vf to VST 802.1ad mode (mlx4 VST QinQ mode) by setting vf vlan protocol to 802.1ad. VST 802.1ad mode in mlx4, is used for STAG strip/insertion by PF, while the CTAG is set by the VF. Read current vlan protocol as part of the vf configuration state. Upon setting vf vlan protocol to 802.1ad, we use a mechanism of handshake to verify that both the vf and the pf driver version support it. The handshake uses the command QUERY_FUNC_CAP: - The vf sets a pre-defined support bit in input modifier. - A pf that supports the feature sends the request to the vf through a pre-defined field in the output mailbox. - In case vf does not support the feature, the pf will fail the control command (in this case, IP link tool command to set the vf vlan protocol to 802.1ad). No change in VST 802.1Q mode. Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net/mlx4_core: Enable device recovery flow with SRIOV In SRIOV, both the PF and the VF may attempt device recovery whenever they assume that the device is not functioning. When the PF driver resets the device, the VF should detect this and attempt to reinitialize itself. The VF must be able to reset itself under all circumstances, even if the PF is not responsive. The VF shall reset itself in the following cases: 1. Commands are not processed within reasonable time over the communication channel. This is done considering device state and the correct return code based on the command as was done in the native mode, done in the next patch. 2. The VF driver receives an internal error event reported by the PF on the communication channel. This occurs when the PF driver resets the device or when VF is out of sync with the PF. Add 'VF reset' capability, which allows the VF to reinitialize itself even when the PF is not responsive. As PF and VF may run their reset flow simulantanisly, there are several cases that are handled: - Prevent freeing VF resources upon FLR, when PF is in its unloading stage. - Prevent PF getting VF commands before it has finished initializing its resources. - Upon VF startup, check that comm-channel is online before sending commands to the PF and getting timed-out.

net/mlx4_core: Activate reset flow upon fatal command cases We activate reset flow upon command fatal errors, when the device enters an erroneous state, and must be reset. The cases below are assumed to be fatal: FW command timed-out, an error from FW on closing commands, pci is offline when posting/pending a command. In those cases we place the device into an error state: chip is reset, pending commands are awakened and completed immediately. Subsequent commands will return immediately. The return code in the above cases will depend on the command. Commands which free and close resources will return success (because the chip was reset, so callers may safely free their kernel resources). Other commands will return -EIO. Since the device's state was marked as error, the catas poller will detect this and restart the device's software stack (as is done when a FW internal error is directly detected). The device state is protected by a persistent mutex lives on its mlx4_dev, as such no need any more for the hcr_mutex which is removed.

mlx4_core: Add support for secure-host and SMP firewall Secure-host is the general term for the capability of a device to protect itself and the subnet from malicious host software. This is achieved by: 1. Not allowing un-trusted entities to access device configuration registers, directly (through pci_cr or pci_conf) and indirectly (through MADs). 2. Hiding M_Key from untrusted entities. 3. Preventing the modification of GUID0 by un-trusted entities 4. Not allowing drivers on untrusted hosts to receive nor to transmit packets over QP0 (SMP Firewall). The secure-host capability depends on firmware handling all QP0 packets, and not passing these packets up to the driver. Any information required by the driver for proper operation (e.g., SM lid) is passed via events generated by the firmware while processing QP0 MADs. Driver support mainly requires using the MAD_DEMUX FW command at startup, where the feature is enabled/disabled through a procedure described in the Mellanox HCA tools package.

mlx4: Implement IP based gids support for RoCE/SRIOV Since there is no connection between the MAC/VLAN and the GID when using IP-based addressing, the proxy QP1 (running on the slave) must pass the source-mac, destination-mac, and vlan_id information separately from the GID. Additionally, the Host must pass the remote source-mac and vlan_id back to the slave, This is achieved as follows: Outgoing MADs: 1. Source MAC: obtained from the CQ completion structure (struct ib_wc, smac field). 2. Destination MAC: obtained from the tunnel header 3. vlan_id: obtained from the tunnel header. Incoming MADs 1. The source (i.e., remote) MAC and vlan_id are passed in the tunnel header to the proxy QP1. VST mode support: For outgoing MADs, the vlan_id obtained from the header is discarded, and the vlan_id specified by the Hypervisor is used instead. For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the "invalid" vlan (0xffff) is substituted when forwarding to the slave.

mlx4_core: Modify driver initialization flow to accommodate SRIOV for Ethernet 1. Added module parameters sr_iov and probe_vf for controlling enablement of SRIOV mode. 2. Increased default max num-qps, num-mpts and log_num_macs to accomodate SRIOV mode 3. Added port_type_array as a module parameter to allow driver startup with ports configured as desired. In SRIOV mode, only ETH is supported, and this array is ignored; otherwise, for the case where the FW supports both port types (ETH and IB), the port_type_array parameter is used. By default, the port_type_array is set to configure both ports as IB. 4. When running in sriov mode, the master needs to initialize the ICM eq table to hold the eq's for itself and also for all the slaves. 5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap. 6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca). VFs obtain their startup information from the PF (master) device via the comm channel. 7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver aborts loading the device. 8. Do not allow setting port type via sysfs when running in SRIOV mode. 9. mlx4_get_ownership: Currently, only one PF is supported by the driver. If the HCA is burned with FW which enables more than one PF, only one of the PFs is allowed to run. The first one up grabs a FW ownership semaphone -- all other PFs will find that semaphore taken, and the driver will not allow them to run.

mlx4_core: Add network flow counters ConnectX devices support a set of flow counters that can be attached to a set containing one or more QPs. Each such counter tracks receive and transmit packets and bytes of these QPs. This patch queries the device to check support for counters, handles initialization of the HCA to enable counters, and initializes a bitmap allocator to control counter allocations.

IB/mlx4: Signal node desc changes to SM by using FW to generate trap 144 The Node Description cannot be changed via MADs (it is read-only). Until now, it was changed in the driver via sysfs, and the new Node Description was simply inserted by the driver into MAD responses (replacing the description returned by FW). System startup scripts use the sysfs interface to change the node description at driver startup to show the hostname, etc. However, this has a race condition: the SM could discover the original FW node description rather than the system-specific description if it queried the port before the startup scripts finish running. For mlx4, we fix this with a new FW command (SET_NODE) that allows passing the new node description to FW. When this command is invoked, FW sends a trap 144 to the SM. When it gets this trap, the SM can query the node to obtain the new node description -- thus eliminating the effects of the race. This patch simply calls SET_NODE command when a new node description is entered via sysfs (thus causing trap 144 to be issued by the FW). We ignore all failures of the SET_NODE command (including those caused by using a device FW that predates the SET_NODE command), since in that case things work just as before.

mlx4_core: Add link type autosensing When a port's link is down (except to driver restart) and the port is configured for auto sensing, we try to sense port link type (Ethernet or InfiniBand) in order to determine how to initialize the port. If the port type needs to be changed, all mlx4 for the device interfaces are unregistered and then registered again with the new port types. Sensing is done with intervals of 3 seconds.

IB/mlx4: Handle FW command interface rev 3 Upcoming firmware introduces command interface revision 3, which changes the way port capabilities are queried and set. Update the driver to handle both the new and old command interfaces by adding a new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware interface revision and then using the correct interface based on the setting of the flag.

IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
