This is not the case. While common wisdom does indeed suggest that BPF is slow it is in fact not the case.

We are currently preparing that software package for public release. -- Andre _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
