Subject: forcing a packet to go through hw net device
Date: Mon, 09 May 2005 14:58:42 +0200 [thread overview]
Message-ID: <200505091458.42118.Jeff@steinhagen.ch> (raw)
Hi!
I have a (maybe trivial) question about the kernel's networking code:
A packet with an "outside" destination goes through all layers including the
hardware interface (user->socket->protocol->IP->HW). However if the packet is
addressed to a local IP the transport through and checks by the hardware
layer are avoided. This is perfectly OK for "normal" network usage.
I am profiling some network hardware and related code. Is it possible to force
an internally generated packet to be send through all/the hardware layers?
Thanks for your help!
Cheers,
Jeff
