Subject:   Netmap and in-kernel IPFW interactions!

Hi Everybody,

I have compiled my kernel with support of netmap without any changes on
ipfw. Afterwards, I defined ipfw rules and surprisingly they worked!!

Before my experiment on ipfw, I'd thought because packets are reached to
userspace directly by means of netmap, so in-kernel ipfw won't be able to
check them in between?!

Could anyone clarify me how in-kernel tools are able to work even after
netmap is used?
