Did something break? It seems to matter most for dumping. But even that
didnt breaking. Looking at the latest net tree, i tried:

====
sudo $TC filter add dev $ETH parent 1: protocol ip prio 10 u32 \
match ip protocol 1 0xff flowid 1:2 \
action skbedit prio 33 \
action ife encode type 0xDEAD \
use mark 12 allow prio dst 02:15:15:15:15:15

Then I dump:
=====
jhs@...-foobar:~$ sudo $TC -s filter ls dev $ETH parent 1: protocol ip
filter pref 10 u32
filter pref 10 u32 fh 800: ht divisor 1
filter pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:2 
(rule hit 12 success 2)
   match 00010000/00ff0000 at 8 (success 2 )
	action order 1:  skbedit priority :33
	 index 2 ref 1 bind 1 installed 604 sec used first 589 sec last 583 sec
  	Action statistics:
	Sent 196 bytes 2 pkt (dropped 0, overlimits 0 requeues 0)
	backlog 0b 0p requeues 0

	action order 2: ife encode action pipe type 0xDEAD
	 use mark 12 allow prio dst 02:15:15:15:15:15
	 index 2 ref 1 bind 1 installed 604 sec used first 589 sec last 583 sec
	Action statistics:
	Sent 196 bytes 2 pkt (dropped 0, overlimits 0 requeues 0)
	backlog 0b 0p requeues 0
