This is a fix to a regression introduced by commit: "982290a net/mlx4_core: Check port number for validity before accessing data" IPoIB could not attach to multicast group and we get this in dmesg: [144214.145008] ib0: failed to attach to multicast group, ret = -22 [144214.145016] ib0: couldn't attach QP to multicast group ff12:401b:ffff:0000:0000:0000:ffff:ffff [144214.145019] ib0: multicast join failed for ff12:401b:ffff:0000:0000:0000:ffff:ffff, status -22 The cause to the problem is because port is extracted from gid[5]. Which is only valid for Ethernet. Removed this validation in mlx4_qp_attach_common(), which is accessed from both Ethernet and IB flows. Error flow for bad port value in Ethernet is already exists in that function.
