Hi,
I'm tryinbg to follow packets flowing up from an ethernet
device driver (if_fxp.c in this case) and as far as I can tell
they are processed completely at device interrupt level unless
deferred in netisr_dispatch(). Is that correct?
Thanks,
George

Sorry for the mistakes (again)... need to sleep :/
Bellow are the right results with the right ip address...
# route add 10.0.10.1 10.0.10.2
results are :
# route get 10.0.10.1
route to: 10.0.10.1
destination: 10.0.10.1
gateway: 10.0.10.2
interface: tap0
# route get 10.0.10.2
Hello,
Thank you very much for the details. I think I'm starting to understand the
subject better.
Well, I've did all again from the beggining and now I have the same results
has you had. It works.
10.0.10.1 is routed via lo0, and 10.0.10.2 is routed via tap0.

This is not the broadcast address for the network you've configured. It
should be 10.0.10.255.

When I sniff lo0, I have this result :
10:09:12 10.0.0.1 > 10.0.0.1: icmp: echo request
10:09:12 10.0.0.1 > 10.0.0.1: icmp: echo reply

I've noticed that in dmesg:
tap0: discard frame w/o leading ethernet header (len 2 pkt len2)
I don't know anything about that (?!?)
Does it works for you when
