I did some similar work for bpf & mmap with NetBSD.

Yes, I saw those.  The guy doing the FreeBSD work appears to be claiming
that he dropped fewer packets with his mapped access, but that might
just be a result of not time-stamping packets (WinPcap, as I remember
offers different time-stamping options, so you can choose accurate or
cheap), or something else making it an apples-to-oranges comparison.
