The new tcpdump is in place in -current. Feel free to check it out and
beat it up.

No problem. There are always confusion printing network number in
decimal, i.e. 0xfffe is printed as 255.254 or 65534. I just disliked
this.
By the way, print-atalk.c is still buggy in handling aarp packet.
I'd like to send a patch to fix it. I diff(1)'ed print-atalk.c of
2.1.5R and mine. Please check and merge below.
Thank you.
