Re: [LARTC] tc filter priority

[Jody Shumaker <jody.shumaker@gmail.com>]

I'm unsure on the order, it might be based on when they were added. 
However if you really want to be sure one gets used before the other
then why don't you use different prio values? a filter with a lower
prio value will get processed before ones with a higher value. If you
want to guarentee one gets processed before another, then use prio as
that's its whole purpose.
