In IPv4, the newly introduced rdma_read_gids is used to read the SGID/DGID for the connection which returns GID correctly for RoCE transport as well. In IPv6, rdma_read_gids is also used. The following are why rdma_read_gids is introduced. rdma_addr_get_dgid() for RoCE for client side connections returns MAC address, instead of DGID. rdma_addr_get_sgid() for RoCE doesn't return correct SGID for IPv6 and when more than one IP address is assigned to the netdevice. So the transport agnostic rdma_read_gids() API is provided by rdma_cm module. Signed-off-by: Zhu Yanjun <yanjun.zhu@xxxxxxxxxx> ---
