netmap-ipfw on em0 em1

[Evandro Nunes]

btw,

I am generating traffic via pkt-gen which I can see os received on the
other side:

# /usr/src/tools/tools/netmap/netmap-7e9e5e7602f5/examples/pkt-gen -i em1

anyway ipfw does not seem to see this netmap-aware traffic:

# ipfw/ipfw show
connected to 127.0.0.1:5555
nalloc 2248 nbytes 112 ptr 0x0
00100 0 0 count ip from any to any
65535 0 0 allow ip from any to any

while it's still running:

# ps wauxw | grep ipfw
root          40820   0.4  0.0  14648   1744  2  R    12:32PM     0:04.95
./kipfw em1 em2 lo0
root          40886   0.0  0.0  14708   1552  2  DL+  12:34PM     0:00.00
grep ipfw

I am using latest netmap and netmap-ipfw source code, not the code from
freebsd base system.

everywhere I see examples, on readme files, luigi's papers and videos, it's
related to vale interfaces, but what I want is to use it in phisical NIC
not a vale NIC

any further help is much appreciated

thank you in advance
