ixgbe: Add a RETA query command to VF-PF channel API Add this new command for 82599 and x540 devices only. Support for other devices will be added later. 82599 and x540 VFs and PF share the same RSS redirection table (RETA). Therefore we just return it for all VFs. For 82599 and x540 RETA table is an array of 32 registers (128 bytes) and the maximum number of registers that may be delivered in a single VF-PF channel command is 15. On the other hand VFs of these devices can be configured to have up to 4 RSS queues. Therefore we will "compress" the RETA by transferring only 2 bits per entry and thereby it will take only 8 registers (DWORDS) to transfer the whole VF RETA. Thus this patch does the following: - Adds a new API version (to specify a new commands set). - Adds the IXGBE_VF_GET_RETA command to the VF-PF commands set.

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.
