Some time ago I wanted to do experiments with a reduced mbuf size, just
for the sake of it. Changing MSIZE (to 128 in this case) and recompiling
the kernel seemed to do the job, although I only tested fairly standard
functionality. This was on a 5.4-RELEASE system.
However, I noticed one probl
I have an unsupported patch for up to gcc 4.0. I'll send it as separate
email to you and will eventually put it on my web page.

I haven't carefully looked into the code, but it seems enable to receive as
well as intercept (and send through a socket to the user-level) packets
Ping Pan has implemented a complete IP options package for FreeBSD versions
up to 4.0. Maybe it's easy to port it to newer versions. See

Thanks, this is fantastic! On all FreeBSD 4.x versions, the performance of
end systems receiving large amounts of small packets used to be much worse
than on FreeBSD 3.4. I'm not a driver expert, but as you described, the
vanilla systems seem to spend too much time in the interrupt context, such

but I don't know the current project status.
I've added rudimentary MPLS signalling support to RSVP (label distribution
and explicit routing according to draft-ietf-mpls-rsvp-lsp-tunnel-07.txt
Thanks for this hint, but it doesn't seem to help. Here's the output of
netstat -m after a test with packet losses:

Greetings,
I have observed the following behaviour on FreeBSD 4.x platforms (4.0 till
4.3 seem to be affected).
