Hi there,

Well I took a look at the scanner.l file, flex can't handle the perl 
like \S syntax, matching negated case did not work either, and my flex 
skillz are no good :(.  The best I could come up with was a horrible 
hack, if someone could please fix my hack and make it really match words.

As far as I experimented you can make interface names with nearly any 
non whitespace chars, as long as they are between 1 and 15 chars long. 
Although I did see flaky "ip link show" reports when an interface was 
called eth0:0:0:0 for instance, but radvd will try to find it anyway.

changing interface name:
zeus:/# ip link set dev "<currentdevname>" name "DA*DA(#"
will work :)

Anyway patch is attached.
