Stef,
Thanks for the reply.
I want my bridge to "emulate" a rate limit on the transmitter of the device
connected to that particular bridge interface. That's why I need an ingress
qdisc on each and every interface of my Linux bridge. This is what I tried:
tc qdisc add dev eth4 handle ffff: ingress
tc filter add dev eth4 parent ffff: protocol ip prio 50 u32 match ip \
src 0.0.0.0/0 police rate 100kbit burst 10k drop flowid :1
I didn't obeserve any rate reduction though. I suspect that on the bridge,
packets are being forwarded and therefore the ip-related matches have no
effect. How can I have the 'police rate 100kbit' portion of the command
without the ip-related arguments?
Thanks,
Marcelo.
