Subject: [PATCH] IB/mlx4: Fix wrong usage of IPv4 protocol for multicast
 attach/detach

The MLX4_PROT_IB_IPV4 protocol should only be used with RoCEv2 and such.
Removing this wrong usage allows to run multicast applications over RoCE.

Fixes: d487ee77740c ("IB/mlx4: Use IBoE (RoCE) IP based GIDs in the port GID table")
