Since someone showed interest, I updated my patches against trunk. :-)
http://people.freebsd.org/~jkim/qemu-pcap-20080717.diff
I turned it off by default for now. If you want to enable it, do:
configure --enable-pcap

*After* applying the new patch:
cp -p vl.c vl.c.orig
sed -e 's/#ifdef PCAP_SET_FILTER/#if 1/g' vl.c > vl.c.tmp
mv vl.c.tmp vl.c
and try again? BTW, I have no real experience with WinPcap, so don't
kill me if it does not work for you. ;-)

Thanks for the tip!

I added WinPcap API support from WinPcap manual pages but I have no
way of checking. Can you try the patch and letting me know?
Juergen,
I made FreeBSD ports patch for emulators/qemu-devel:

FYI...
Thanks,
