> Mbps(megabits per second).
> 
> Mbps max-rate is set for the queue via sysfs:
> /sys/class/net/<iface>/queues/tx-<queue>/tx_maxrate
> ex: echo 100 >/sys/class/net/ens7/queues/tx-0/tx_maxrate
>     echo 200 >/sys/class/net/ens7/queues/tx-1/tx_maxrate
> Note: A value of zero for tx_maxrate means disabled,
> default is disabled.
