	You probably have to apply more fixes to be sure something
will not break. I just uploaded some fixes for the 2.2 code as
it appears nobody have the time to deal with it:

	To all: if there is a good place for such fixes please let
me know.

	Not "very similar" :) The bug is exactly in the
differences :)

	mark here is in decimal (may be can be hex with 0x20):

	"handle 20" here is in hex:

> tc filter add dev eth0 parent ffff: protocol ip prio 50 handle 20 fw

	if you somewhere use fwmark in ip rules, the fwmark
there is again in hex. Make sure all values match according
to their representation, i.e. 20 in dec is different from
20 in hex.
