Dear sir:
    I have followed the instructions"To set up software RDMA on an existing interface with either of the available drivers, use the following commands, substituting <DRIVER> with the name of the driver of your choice (rdma_rxe or siw) and <TYPE> with the type corresponding to the driver (rxe or siw).
# modprobe <DRIVER>
# rdma link add <NAME> type <TYPE> netdev <DEVICE>

Please note that you need version of iproute2 recent enough is required for the command above to work.
You can use either ibv_devices or rdma link to verify that the device was successfully added."
but when I execute rdma link add, it cann't find the command, so how can i solve it. Thank you very much!
my commands history is showed as below.

The solution is written in the first sentence "Please note that you need version
of iproute2 recent enough is required for the command above to work."

Thanks
