Ivan Khoronzhuk 83fcad0c98 net: ethernet: ti: cpsw: add .ndo to set per-queue rate 
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
