Subject: [PATCH 08/10] net: phy: genphy: always write MII_CTRL1000 when available
Date: Wed, 21 May 2014 14:18:58 +0200	[thread overview]
Message-ID: <1400674740-6467-9-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1400674740-6467-1-git-send-email-s.hauer@pengutronix.de>

the phydev->supported field does not necessarily match the hardware
capabilities, it could be limited by the board to force the phy
to a lower speed. In this case make sure the gigabit advertise bits
are cleared on a gigabit phy.
