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 Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Siddharth Vadapalli <s-vadapalli@ti.com> Link: https://lore.kernel.org/r/20230327085758.3237155-1-s-vadapalli@ti.comSigned-off-by: Paolo Abeni <pabeni@redhat.com>
