[PATCH iproute2-next v1 4/4] rdma: Add support to get MR in raw format

[Leon Romanovsky]

From: Maor Gottlieb <ma...@mellanox.com>

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",
"data":[0,4,255,254,0,0,0,0,0,0,0,0,16,28,0,216,...]}]
