From: Sathya Perla <sathyap@...verengines.com>
To: netdev <netdev@...r.kernel.org>
Subject: [net-next-2.6 PATCH] be2net: fix some cmds to use mccq instead of
mbox
All cmds issued to BE after the creation of mccq must now use the mcc-q
(and not mbox) to avoid a hw issue that results in mbox poll timeout.
