I don't doubt that the bridging code, and iptables/ebtables is nearly 
the same, but _something_ is different. (Kernel .config options, QoS 
code, 2.4/2.6 interface, aliens abducting sk_buff->nfmark, I dunno...) 
The same system booted with a 2.4 kernel and a 2.6 kernel behave 
differently. 2.6 was configured with similar options to 2.4. (make 
oldconfig -> Maybe there's a new option somewhere that I'm missing?)

As far as I can see, bridged traffic control on 2.4 works, 2.6 doesn't:

"tc -s class show dev eth0" on a 2.4 kernel shows packets being 
classified properly, whereas on 2.6, they are not classified properly.

I actually think iptables/ebtables is working properly; In 2.6, ebtables 
does indeed count the correct number of packets passing through each 
rule, and assuming that "-j mark" actually marks them, the only possibly 
answer would be that the tc stuff isn't catching those marks.

I'd be really happy to hear any suggestions or ideas, 'cause I'd really 
love to get 2.6 working! If there's _anything_ I can do that might help 
debug this stuff, I'd be glad to try.

Cheers,
