Daring to challenge the will of the almighty Leviam00se,
Manu Iyengar (iyengar@galaxy.ee.rochester.edu) had the courage to say:
: I'm probably missing something obvious here, but...
: Box: FreeBSD 2.0.5
: Ethernet Card: Intel EtherExpress 16 (ix0)
: I added the following line to my kernel conf and recompiled:
: pseudo-device bpfilter 8 # Berkeley packet filter
: That should enable the BPF. However, on trying to run tcpdump:
: grunthos-19:07-[~]-18 % tcpdump
: tcpdump: ix0: Device not configured
^^^
You're not missing anything: it's the Intel EtherExpress 'ix' driver
that's missing something. It doesn't yet include BPF support. It's
also a little rough around the edges (though it works pretty well
all things considered). Rod Grimes, the driver's author, is one
of the busier members of the core team (to put it charitably) and
consequently hasn't had time to add this support. If anyone out there
knows something about Intel EtherExpress cards (and isn't bound by
any stupid non-disclosure agreements) feels like adopting this driver
and refining it a bit, we'd love to hear from you.
