Fwd: Linux bridge on linksys WRT54GS running OpenWRT

Hi ebtables dev team,

Has you can see bellow we reported a problem with bridging and MLD
reports using bridge to bridge mailing list, but it seems more related
to ebtables.

Can you have a look to this issue?

The problem can be easily reproduced. Do not hesitate if you need help to do it.

Thanks

Sebastien

The netfilter interface is really the responsibility of the ebtables
project. I maintain the hooks for them, but what happens in the filters
is their doing.

If you want put a link on http://linux-net.osdl.org on the bridge page.
