To allow this, several changes were required. First of all, there is a need to validate MLID when link layer is Infiniband. This check is mandatory according to Infiniband spec but the MLID should be ignored for RoCE according to RoCEv2 Annex (Annex 17, A17.5.6). Second, there is need to cange the mapping of IPv4 multicast addresses to MGIDs to be according to RoCEv2 Annex (A17.4.1.1 L3 Addresses): GID = ::ffff: And third, multicast addresses need to be mapped to multicast MAC instead of searching for it in the GID table.
