rdma resource help
rdma resource show - display rdma resource tracking information
DEV/PORT_INDEX - specifies the RDMA link to show. If this
argument is omitted all links are listed.
rdma resource set - configure resource related parameters
DEV - specifies the RDMA device to configure.
AGING_PERIOD - specifies the aging period in seconds for unused
FRMR handles. Handles unused for this period will be freed.
POOL_KEY - specifies the pool key that identifies a specific FRMR
pool. The key is a colon-separated list of hexadecimal fields in
the format vendor_key:num_dma_blocks:access_flags:ats.
PINNED_VALUE - specifies the pinned value for the FRMR pool. A
non-zero value pins handles to the pool, preventing them from
being freed by the aging mechanism.

Set the aging period for FRMR pools on device rocep8s0f0 to
120 seconds.
rdma resource set frmr_pools dev rocep8s0f0 pinned 0:1000:0:0
25000
Pin 25000 handles to the FRMR pool identified by key
0:1000:0:0 on device rocep8s0f0 to prevent them from being
freed.
