Hi Corey.

I did it on your recommendation, replaced xtables.h file from my
version of iptables 1.6.0, and replaced the file netfilter.h.

Now it's works, but new construction doesn't:

# tc filter add dev eth0 parent ffff: u32 match u32 0 0 action xt -j
SET --map-set WORLD_QoS dst
xt: unrecognized option '--map-set'
failed to find target (null)

bad action parsing
parse_action: bad value (6:xt)!
Illegal "action"

my ipset chain:
# ipset -L WORLD_QoS
Name: WORLD_QoS
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536 skbinfo
Size in memory: 96

------------------------------------------------

If I will try to execute:

# tc filter add dev eth0 parent ffff: u32 match u32 0 0 action xt -j SET

tc-ipt v0.2: You must specify either `--add-set' or `--del-set' or `--map-set'

it looks like it possible to use this construction.

Is it possible?
