netmap-ipfw on em0 em1

[Evandro Nunes]

hello,
I am trying to do some basic stateless filtering with netmap-ipfw.

what i have running is:

./kipfw em1 em2 lo0

and when i do ipfw/ipfw show:

ipfw/ipfw show
connected to 127.0.0.1:5555
nalloc 2248 nbytes 136 ptr 0x0
00100 0 0 allow ip from any to any via lo0
65535 0 0 allow ip from any to any

it's not counting any packet, including loopback

i have seem people using something similar but with ix(4) driver, what I am
doing wrong?
