I've applied the patch to my iproute2 that was suggested as a solution, as well as upgrading to the latest version (http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.14-051107.tar.gz) of iproute2 which includes the patch, but always get the following errors:
# tc qdisc add dev eth1 handle 1:0 root dsmark
indices 64
RTNETLINK answers: Invalid
argument
Changing that to:
# tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index
Works, but following that with produces the same error:
# tc class change dev eth1 classid 1:1 dsmark
mask 0x3 value 0x88
RTNETLINK answers:
Invalid argument
Is this an iproute2 bug, or user error?
I'm using iproute2 on FC4 2.6.14-1.1653
