Does that mean, I cannot use the tc filter command with IPv6?
How can I shape without filter?
The attached script "setup-01.tc.sh" works fine with v4. The traffic is
shaped according to the qdisc tbf settings.
With v6 these setting move all packets to the class, the prio-map maps
the Best-Effort traffic to.
Is this because the tc filter on the destination ports already fails?
$TC filter replace $DEV parent 1:0 protocol ip prio 1 u32 \
match ip dport $VIDEO_PORT 0xffff flowid 1:2

Yes, MARK seems to work ("Edge1new.sh").
ip6tables -I OUTPUT -t mangle -p udp --destination-port 5001 \
-j MARK --set-mark 1
ip6tables -L OUTPUT -t mangle
... lists the desired settings. But again
$TC filter add $EGDEV parent 1:0 protocol ip prio 4 handle 1 fw
classid 1:1
does not what it should.
What do you mean by shaping on fw-mark? Is that possible without using
tc filter?
