Subject: USB gadget: drain rndis response queue on disconnect
Date: Tue, 24 May 2005 17:51:52 -0700
To: "Andy Lowe" <alowe@mvista.com>, Greg KH <greg@kroah.com>
Message-Id: <200505241751.52227.david-b@pacbell.net>
Drain the rndis response queue on disconnect. This fixes a problem
in which an rndis response left in the queue from a previous session
could cause a subsequent session to fail.
