Subject: [PATCH RFC for-next 3/3] RDMA/hns: Support SRQ restrack ops for hns driver
From: wenglianfa <wenglianfa@...wei.com>
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,
46,62,31,0,0,0,0,3,0,0,1,0,58,62,31,0,0,0,0,
30,159,15,0,0,0,64,5,0,0,0,0,0,0,0,0,0,0,0,
9,0,0,0,0,0,0,0,0 ]
} ]
