Bug#532727: iproute: "tc filter add ... protocol ip fw" broken?

[Marek Michalkiewicz]

Package: iproute
Version: 20090324-1
Severity: normal

Trying to add a tc filter based on iptables mark (useful with IPMARK
from xtables-addons to replace many rules with a single efficient one):

# tc qdisc add dev eth0 root handle 1: htb
# tc filter add dev eth0 parent 1: protocol ip fw
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
# tc filter show dev eth0
filter parent 1: protocol ip pref 49152 fw

So, the filter is still added despite the error.
iproute 20061002-3 (from oldstable) worked fine,
iproute 20080725-2 (from stable) and the latest 20090324-1 doesn't.

I'm not the only one with this issue - it is discussed here too:
http://forum.soft32.com/linux/tc-filter-fw-26-problem-ftopict469017.html

Tried on 2.6.26 from stable too, same results. Not sure where the bug
really is (iproute or kernel), please reassign as appropriate.
