This is the 6th version of our interface group patches.

The interface group value can be used to manage different interfaces
at the same time such as in netfilter/iptables.

I take it you could not use...?
	iptables -i iif1 -j dosomething
	iptables -i iif2 -j dosomething

This kind of usage requires static interface names. But there are 
dynamic interfaces such as ppp, where the actual name is not always 
known or sometimes they exist sometimes not. It is difficult to use 
iptables this way, and every ifup/ifdown requires change in the iptables 
ruleset (donwload it, modify and upload to the kernel). It may be too slow.

This is actually not true these days.

When network devices are created user events are generated and the
user can rename the device however they like using a mapping table of
any kind.

And at such point the problem you present doesn't actually exist, you
can know what the device will be named.

And if rule loading dynamically is slow, we should fix that instead of
creating infrastructure and interfaces we don't actually need.
