[PATCH 16/30] RDMA/ocrdma: changes to support RoCE-v2 in RC path
From: Devesh Sharma devesh.sha...@emulex.com
To support RoCE-V2 this patch implements following changes
1. Get the GID-type for a given sgid.
2. Based on the gid type get IPv4 L3 address
and give those to FW.
3. Provide l3-type to FW.
