Subject: [wt PATCH 1/5] libertas: get the right # of scanned BSSes
Date: Thu, 29 Jul 2010 23:11:30 -0700	[thread overview]
Message-ID: <1280470290.14523.7.camel@dcbw.foobar.com> (raw)
In-Reply-To: <1280470034.14523.4.camel@dcbw.foobar.com>

Let's actually check the right field in the command response; and
if there aren't any reported BSSes, exit early with success.
