ice: Add NDO callback to set the maximum per-queue bitrate
Allow for rate limiting Tx queues. Bitrate is set in
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.
