>Description:
	NetBSD libpcap has extension to support arcnet.  this is
	defined in scanner.l as "AID", and the regex for this is ":{B}"
	(colon, and then hexadecimals).
	Unfortunately, libpcap uses ":" to special purpose, for byte
	range in protocol header.  AID definition conflict with it, and
	raises incompatible behavior with other libpcap.
>How-To-Repeat:
	# tcpdump -n 'ip[2:2] > 576'
	it will raise syntax error on NetBSD, not on other systems.  This
	example is present on tcpdump(8).
>Fix:
	- change syntax for arcnet address.
	- disable arcnet support.
	- what others?
