Set max rate-limit using sysfs file /sys/class/net/<interface>/qos/ratelimit

To set, enter a space separated list of values in units of 100Mbps.  For
example to set ratelimit of 5G to TC0 and 10G for the reset on eth2 issue:
echo 50 100 100 100 100 100 100 100 100>  /sys/class/net/eth2/qos/ratelimit

Oh thats not very user friendly.

I suggest one value per file (Its probably a generic /sys rule anyway)
and not using 100Mps for the unit, even if it is the base granularity of
this hardware.


/sys/class/net/eth2/qos/0/ratelimit
...
/sys/class/net/eth2/qos/7/ratelimit

Ok, will change the structure to be:

/sys/class/net/eth2/qos/tc0/ratelimit
...
/sys/class/net/eth2/qos/tc7/ratelimit

And use units of 1Mbps
