RDMA/nldev: Return SRQ information
Extend the RDMA nldev return a SRQ information, like SRQ number, SRQ type, PD number, CQ number and process ID that created that SRQ. Sample output: $ rdma res show srq dev ibp8s0f0 srqn 0 type BASIC pdn 3 comm [ib_ipoib] dev ibp8s0f0 srqn 4 type BASIC pdn 9 pid 3581 comm ibv_srq_pingpon dev ibp8s0f0 srqn 5 type BASIC pdn 10 pid 3584 comm ibv_srq_pingpon dev ibp8s0f0 srqn 6 type BASIC pdn 11 pid 3590 comm ibv_srq_pingpon dev ibp8s0f1 srqn 0 type BASIC pdn 3 comm [ib_ipoib] dev ibp8s0f1 srqn 1 type BASIC pdn 4 pid 3586 comm ibv_srq_pingpon Link: https://lore.kernel.org/r/322f9210b95812799190dd4a0fb92f3a3bba0333.1618753110.git.leonro@nvidia.com Signed-off-by: Neta Ostrovsky <netao@nvidia.com> Reviewed-by: Mark Zhang <markzhang@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
