Hmm, none that I can think of, other than mesh support.  I wrote this to
test some code refactoring I was doing in this area, but it should have
also worked before the changes.

I guess it could fail if the 'iw' command didn't work as expected, or if
there's a timing issue and the gate announcements aren't received.

With today's wireless-testing, it's passing for me (the "+" is just for
some whitespace fixes that aren't upstream yet):

Got a different kernel version or config I should try?
