RDMA/ocrdma: Support RoCE-v2 in the UD path
This patch adds following changes to support RoCE-v2
in the UD path.
* During AH creation GID-type is resolved for a given gid-index.
* Based on GID-type protocol header is built.
* Work completion reports network header type and set
IB_WC_WITH_NETWORK_HDR_TYPE flag in wc->wc_flags to indicate
that the network header type is valid.
