 Then that check can probably be removed - OpenBSD's consumers might  
 all use bpf_maxbufsize, so it was OK for them, and it's just an  
 optimization anyway (as the comment says, a "More strict check with  
 actual packet length is done runtime").
 
 (BTW, this was from OpenBSD; if you check it in, say it's from Otto  
 Moerbeek's changes to OpenBSD, do *NOT* give me direct credit for it!)
