RDMA/hns: Support SRQ restrack ops for hns driver
The SRQ restrack attributes come from the context maintained by ROCEE.
Example:
$ rdma res show srq -jp -dd
[ {
"ifindex": 0,
"ifname": "hns_0",
"srqn": 0,
"type": "BASIC",
"lqpn": [ "14-15","22-23" ],
"pdn": 2,
"pid": 1224,
"comm": "ib_send_bw",{
"drv_srqn": 0,
"drv_wqe_cnt": 512,
"drv_max_gs": 2,
"drv_xrcdn": 0
}
} ]
$ rdma res show srq link hns_0 -jpr
[ {
"ifindex": 0,
"ifname": "hns_0",
"data": [ 149,0,0,0,0,0,0,0,0,0,0,0,119,101,120,99,0,
