From: Maor Gottlieb <maorg@xxxxxxxxxxxx>
Add the required support to print MR data in raw format.
Example:
$rdma res show mr dev mlx5_1 mrn 2 -r -j
[{"ifindex":7,"ifname":"mlx5_1","mrn":2,"mrlen":4096,"pdn":5, pid":24336,
"comm":"ibv_rc_pingpong","data":[0,4,255,254,0,0,0,0,0,0,0,0,16,28,0,216,...]}]
