IB/mlx4: Handle IPv4 header when demultiplexing MAD

Browse source

When MAD arrives to the hypervisor, we need to identify which slave it
should be sent by destination GID. When L3 protocol is IPv4 the
GRH is replaced by an IPv4 header. This patch detects when IPv4 header
needs to be parsed instead of GRH.

Fixes: b6ffaeffae ('mlx4: In RoCE allow guests to have multiple GIDS')
