It looks like the bridge netfilter code does not correctly update
the hardware checksum after popping off the VLAN header.
This is by inspection, I have *not* tested this.
To test you would need to set up a filtering bridge with vlans
and a device the does hardware receive checksum (skge, or sungem)
