ixgbevf: Mailbox improvements Improve reliability of the mailbox communication and remove its potential flaws that may lead to the undefined or faulty behavior. Recently some users reported issues on ESX with 10G Intel NICs which were found to be caused by incorrect implementation of the PF-VF mailbox communication. Technical investigation highlighted areas to improve in the communication between PF or VF that wants to send the message (sender) and the other part which receives the message (receiver): - Locking the mailbox when the sender wants to send a message - Releasing the mailbox when the communication ends - Returning the result of the mailbox message execution Signed-off-by: Radoslaw Tyl <radoslawx.tyl@intel.com> Tested-by: Tony Brelinski <tony.brelinski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

ixgbe, ixgbevf: Add new mbox API xcast mode The limitation of the number of multicast address for VF is not enough for the large scale server with SR-IOV feature. IPv6 requires the multicast MAC address for each IP address to handle the Neighbor Solicitation message. We couldn't assign over 30 IPv6 addresses to a single VF. This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE, to update multicast mode of VF. This adds 3 modes; - NONE only L2 exact match addresses or Flow Director enabled - MULTI BAM and ROMPE set - ALLMULTI BAM, ROMPE and MPE set If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI to request PF to update xcast mode to enable VF multicast promiscuous mode. On the other hand, enabling VF multicast promiscuous mode may affect security and performance in the network of the NIC. Only trusted VF can enable multicast promiscuous mode. The behavior of untrusted VF is the same as previous version.

net, ixgbe: handle link local multicast addresses in SR-IOV mode In SR-IOV mode the PF driver acts as the uplink port and is used to send control packets e.g. lldpad, stp, etc. eth0.1 eth0.2 eth0 VF VF PF | | | <-- stand-in for uplink | | | -------------------------- | Embedded Switch | -------------------------- | MAC <-- uplink But the embedded switch is setup to forward multicast addresses to all interfaces both VFs and PF and onto the physical link. This results in reserved MAC addresses used by control protocols to be forwarded over the switch onto the VF. In the LLDP case the PF sends an LLDPDU and it is currently being forwarded to all the VFs who then see the PF as a peer. This is incorrect.

ixgbevf: Add support for VF API negotiation This change makes it so that the VF can support the PF/VF API negotiation protocol. Specifically in this case we are adding support for API 1.0 which will mean that the VF is capable of cleaning up buffers that span multiple descriptors without triggering an error.

ixgbevf: Cleanup handling of configuration for jumbo frames This change moves the code for notifying the PF of the VF maximum packet size into the vf.c file. The main motivation behind this is that the vf.c file is supposed to contain all of the messages used when communicating with the PF. In addition it creates a separate function for setting the Rx buffer size so that we have on centralized area to review what buffer sizes will be requested by the VF.

ixgbevf: Fix mailbox interrupt ack bug Remove jump to out label that was skipping over code to replace the ack bit in the mailbox cache variable. This was causing driver mailbox routines that poll for the PF to ack a message to time out which would in turn cause all other mailbox messages to fail. Also replace the mailbox cache variable message indication bit when a message is found so that other functions that choose to poll for a mailbox message from the PF won't miss it.
