I had a similar problem not long ago. Make sure that ip_conntrack is not
loaded. In my case, it was re-assembling all fragmented packets passing
through the bridge, and not fragmenting them again. The resulting large
packet was too big for the interface, and it got dropped.

Subject: 802.1q packets
Hi,
I notice that with the Kernel 2.6.25.9 the 802.1q VLAN
tagged packets larger than 1470 bytes are not forwarded at
all by a bridge.
I think there is a bad interaction between bridge and
netfilter codes. Any chance to a have a patch to solve this
problem that limit the possibility to use the Linux bridges
in a environment with VLANs?
Best Regards
Fulvio Ricciardi
