Subject: [PATCH] bcm43xx: Fix loss of association after resume
Date: Fri, 09 Feb 2007 10:18:03 -0600	[thread overview]
Message-ID: <45cc9ebb.+9O/IXvs/C9RyFnk%Larry.Finger@lwfinger.net> (raw)

After a suspend/resume cycle, bcm43xx-softmac has lost its association with
the AP and requires manual intervention. This situation is fixed by making
one of softmac's internal routines public and calling it.
