rdma resource help

Description

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.
