Message-Id: <1390360813-29185-2-git-send-email-chris.ruehl@gtsys.com.hk> Date: Wed, 22 Jan 2014 11:20:13 +0800 From: Chris Ruehl <chris.ruehl@...ys.com.hk> To: netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, davem@...emloft.net, Chris Ruehl <chris.ruehl@...ys.com.hk> Subject: [PATCH 2/2] net: dm9000: Only call PHY reset for TYPE-B on shutdown Unconditional call of PHY reset can triggers a fault to detect the link for DM9000A on reboot, only a hard reset can solve it. This patch check the version of the chip and call the PHY reset only for the B version of the chip.
