From: Talat Batheesh <talatb@xxxxxxxxxxxx>
For Raw Packet QP, the AV attribute is passed in INIT to RTR in order
to set the Ethernet Priority using the SL. The rest of the fields
aren't necessarily valid, which causes the ib_resolve_eth_dmac to fail.
Since no release address resolution is needed, don't do anything in
ib_resolve_eth_dmac for Raw Packet QP.
Fixes: dbf727de7440 ('IB/core: Use GID table in AH creation and ...')
