 I think you don't even need any new netfilter patches or features.

Just using "physdev" together with the "quota" match should be
sufficient (maybe it's not in the 2.6.18 kernel, but definitely in
recent or pv_ops kernels).

In addition, I don't think that the netfilter will be interested in a
quota patch to physdev; physdev is meant to match the device a packages
was coming from on a bridge - quotas are definitely the job of the quota
match or QoS, not the physdev match.

Felix
