Subject: RDMA/core: Update query_gid documentation for HCA drivers
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=72e1ff0fb7e09c34956e4b3f619481da4d9787c1;p=openwrt%2Fstaging%2Fblogic.git

RDMA/core: Update query_gid documentation for HCA drivers

query_gid() should return right GID value for iWarp and IB link layers.
It is a no-op for RoCE link layer.  Update the documentation to reflect
this.
