Re: [PATCH] pkt_sched: act_xt support new Xtables interface

Could be your setup. I didnt do a lot of testing but
from my notes (running different kernel at the moment):

#try to point to everything (no iptables setup)
tc filter add dev eth0 parent ffff: protocol ip u32 match u32 0 0 flowid 
23:23 action xt -j CONNMARK --restore-mark
#let it run for a 1 sec then display with
tc -s filter show dev eth0 parent ffff:

----
filter protocol ip pref 49152 u32
filter protocol ip pref 49152 u32 fh 800: ht divisor 1
filter protocol ip pref 49152 u32 fh 800::800 order 2048 key ht 800 bkt 
0 flowid 23:23
   match 00000000/00000000 at 0
	action order 1: tablename: mangle  hook: NF_IP_PRE_ROUTING
	target  CONNMARK restore
	index 1 ref 1 bind 1 installed 3 sec used 1 sec
	Action statistics:
	Sent 280 bytes 4 pkt (dropped 0, overlimits 0 requeues 0)
	backlog 0b 0p requeues 0
