Subject: [PATCH 5/5] P2020rdb: eTSEC2 support
Date: Thu, 20 Sep 2012 17:31:09 +0100 [thread overview]
Message-ID: <1348158669-14034-6-git-send-email-renaud.barbier@ge.com> (raw)
In-Reply-To: <1348158669-14034-1-git-send-email-renaud.barbier@ge.com>
The mdio bus is registered before adding the gianfar interface.
Also the eTSEC2 is configured. Either eTSEC2 or eTSEC3 can now be
used.
