From: Erez Alfasi <ereza@xxxxxxxxxxxx>
Provide an ODP explicit/implicit type indicator
as part of 'rdma resource mr show' dump.
For example:
~$: rdma resource mr show
dev mlx5_0 mrn 1 rkey 0xa99a lkey 0xa99a mrlen 50000000
pdn 9 pid 7372 odp explicit comm ibv_rc_pingpong
For non-ODP MRs, we won't print "odp ..." at all.
