Bug 92694

 
 Below is a patch (apply it with -p0 in /usr/ports/net directory please)
 for update of net/trafshow from 5.2.1 to 5.2.2. There is not a functional
 change from 5.2.1 to 5.2.2 (it was just preparation for gcc 4.0), however
 the patch contains much better workaround for bpf non-blocking brokenness
 in FreeBSD's kernel (kern/84823). Now it should produce results like
 trafshow3 with much better interactivity, IPv6 and some other possibilities.
