Subject: RDMA/CMA: Add rdma_port_space to UAPI
Patch-mainline: v4.17-rc1
Git-commit: 2253fc0caa800ba7c1e380446eb3fb7958a85b93
References: bsc#1103992 FATE#326009
Since the rdma_port_space enum is being passed between user and kernel for
user cm_id setup, we need it in a UAPI header. So add it to
rdma_user_cm.h.
This also fixes the cm_id restrack changes which pass up the port space
value via the RDMA_NLDEV_ATTR_RES_PS attribute.
Fixes: 00313983cda6 ("RDMA/nldev: provide detailed CM_ID information")
