Subject: [PATCH iproute2-next 1/2] rdma: Add "stat show mr" support
From: Erez Alfasi <ereza@...lanox.com>
Show MR counters statistics. Filters are also enabled.
Examples:
~$: rdma stat show mr
dev mlx5_0 mrn 8 page_faults 1221 page_invalidations 0
dev mlx5_0 mrn 9 page_faults 1221 page_invalidations 0
~$: rdma stat show mr mrn 8
dev mlx5_0 mrn 8 page_faults 1221 page_invalidations 0
