net: ethernet: ti: am65-cpsw: add .ndo to set dma per-queue rate
Enable rate limiting TX DMA queues for CPSW interface by configuring the
rate in absolute Mb/s units per TX queue.
Example:
ethtool -L eth0 tx 4
echo 100 > /sys/class/net/eth0/queues/tx-0/tx_maxrate
echo 200 > /sys/class/net/eth0/queues/tx-1/tx_maxrate
echo 50 > /sys/class/net/eth0/queues/tx-2/tx_maxrate
echo 30 > /sys/class/net/eth0/queues/tx-3/tx_maxrate
# disable
echo 0 > /sys/class/net/eth0/queues/tx-0/tx_maxrate
