Subject: [PATCH] sky2: remove restarting workaround flag
Date: Fri, 14 Aug 2009 16:33:17 -0700 [thread overview]
Message-ID: <20090814163317.3c5b5942@nehalam> (raw)
In-Reply-To: <20090814.154154.53636130.davem@davemloft.net>
The whole restarting flag was introduced by Mike McCormack
and was a temporary duct tape patch around issues with transmits
inflight during restart. The problems it was covering are now
fixed and the code should have been reverted.
