From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>
The av->net_type is not initialized before it is checked in
irdma_modify_qp_roce. This leads to an incorrect update to the ARP cache
and QP context. RoCEv2 connections might fail as result.
Set the net_type using rdma_gid_attr_network_type.
Fixes: 80005c43d4c8 ("RDMA/irdma: Use net_type to check network type")
