[Dnsmasq-discuss] Tag from interface name?

[Brian Rak]

I'd like to be able to classify DHCP requests based on the interface 
they come in on.  I'd like to have a tag based on the interface name 
(so, if the request came in over br0, I'd have a br0 tag to match on).

Is there any way of accomplishing this with dnsmasq currently?  My 
interfaces don't actually have an IP address assigned, so I can't match 
by IP.
