I'm not sure it's anything broken with FreeBSD; more likely, it's that the
stack changed and the fingerprints haven't been updated. If I had to
guess, it's the current flavor of syncookies/syncache. Not sure how you
report new signatures to Netcraft -- nmap seems to do the right thing.
Any time there are observable changes in a network stack, fingerprinting
techniques are likely to get confused.
