Message

Provide an option for vendor drivers to get the HW GID context
from the ib_gid_attr during modify_qp and create_ah. Required
for drivers/HW that maintains HW gid index different than the
host sgid_index.

Please review and merge

Thanks,
Selvin Xavier

v2 -> v3:
 Added a new symbol to retrieve the hw context.

v1 -> v2:
 Addressed review comments from Parav

Selvin Xavier (2):
  RDMA/core: Add helper function to retrieve driver gid context from gid
    attr
  RDMA/bnxt_re: Use rdma_read_gid_hw_context to retrieve HW gid index
