This is somewhat inconsistent with the iproute patch which targets
specific groups (with names).
Should iptables be allowed to read "/etc/iproute2/rt_ifgroup"?
There is no standard API like getservbyname()...

I do have a draft patch for physdev which is however against
iptables-1.3.8 and linux-2.6.19 so it will need some more work
but I will attach it for discussion.

(This will leave ebtables to be touched...)

Best regards,
