This patch allows to rate limit queues tx queues for cpsw interface. The rate is set in absolute Mb/s units and cannot be more a speed an interface is connected with. The rate for a tx queue can be tested with: ethtool -L eth0 rx 4 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 tc qdisc add dev eth0 root handle 1: multiq tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip\ dport 5001 0xffff action skbedit queue_mapping 0 tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip\ dport 5002 0xffff action skbedit queue_mapping 1 tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip\ dport 5003 0xffff action skbedit queue_mapping 2 tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip\ dport 5004 0xffff action skbedit queue_mapping 3 iperf -c 192.168.2.1 -b 110M -p 5001 -f m -t 60 iperf -c 192.168.2.1 -b 215M -p 5002 -f m -t 60 iperf -c 192.168.2.1 -b 55M -p 5003 -f m -t 60 iperf -c 192.168.2.1 -b 32M -p 5004 -f m -t 60 Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.
