the variable octeon_mdiobus_driver to the function
.init.text:octeon_mdiobus_probe()

This fixes it.

Subject: micrel phy driver - updated(1)

Hello all:

This patch fixes what Ben mentioned, namely duplicated ids.

From: David J. Choi <david.choi@micrel.com>

Body of the explanation: This patch has changes as followings;
 -support the interrupt from phy devices from Micrel Inc.
 -support more phy devices, ks8737, ks8721, ks8041, ks8051 from Micrel.
 -remove vsc8201 because this device was used only internal test at Micrel.

Subject: net: preserve ifreq parameter when calling generic phy_mii_ioctl().

The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

From c1f19b51d1d87f3e3bb7e6648f43f7d57ed2da6b Mon Sep 17 00:00:00 2001
From: Richard Cochran
Date: Sat, 17 Jul 2010 08:49:36 +0000
Subject: net: support time stamping in phy devices.

This patch adds a new networking option to allow hardware time stamps
from PHY devices. When enabled, likely candidates among incoming and
outgoing network packets are offered to the PHY driver for possible
time stamping. When accepted by the PHY driver, incoming packets are
deferred for later delivery by the driver.

The patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl
and callbacks for transmit and receive time stamping. Drivers may
optionally implement these functions.

Subject: phy/marvell: add 88e1121 interface mode support

This patch adds support for RGMII RX/TX delay configuration on marvell 88e1121
and derivatives.  With this patch, PHY_INTERFACE_MODE_RGMII_*ID modes are now
supported on these devices.

Subject: phy/marvell: add 88ec048 support

Marvell 88ec048 is a derivative of its 88e1121r device.  From the programmer's
perspective, the one major difference is the addition of an additional control
bit in Page 2 Register 16 - used to control the padding of odd nibble
preambles.

This patch adds support for this new device, while inheriting as much code as
possible from the existing 88e1121r implementation.
