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.
