Joe Perches 574e2af7c0 include: Convert ethernet mac address declarations to use ETH_ALEN
It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).

Add #include <linux/if_ether.h> as necessary.

Mathieu J. Poirier c326de88b8 net: allow shifted access in smsc911x V2
This is a revised patch that permits a shifted access to the
LAN9221 registers.  More specifically:

 It adds a shift parameter in the platform_data.
 It introduces an ops in smsc911x_data.
 A choice of access function to use at run-time.
 Four new shifted access function.

Magnus Damm 833cc67c77 smsc911x: add fifo byteswap support V2
This is V2 of the smsc911x fifo byteswap patch.

The smsc911x hardware supports both big and little and endian
hardware configurations, and the linux smsc911x driver currently
detects word order.

For correct operation on big endian platforms lacking swapped
byte lanes the following patch is needed. Only fifo data is
swapped, register data does not require any swapping.

Steve Glendinning 31f4574774 smsc911x: allow mac address to be saved before device reset
Some platforms (for example pcm037) do not have an EEPROM fitted,
instead storing their mac address somewhere else.  The bootloader
fetches this and configures the ethernet adapter before the kernel is
started.

This patch allows a platform to indicate to the driver via the
SMSC911X_SAVE_MAC_ADDRESS flag that the mac address has already been
configured via such a mechanism, and should be saved before resetting
the chip.

Steve Glendinning d23f028a4d smsc911x: add external phy detection overrides
On LAN9115/LAN9117/LAN9215/LAN9217, external phys are supported.  These
are usually indicated by a hardware strap which sets an "external PHY
detected" bit in the HW_CFG register.

In some cases it is desirable to override this hardware strap and force
use of either the internal phy or an external PHY.  This patch adds
SMSC911X_FORCE_INTERNAL_PHY and SMSC911X_FORCE_EXTERNAL_PHY flags so a
platform can indicate this preference via its platform_data.

Steve Glendinning fd9abb3d97 SMSC LAN911x and LAN921x vendor driver
Attached is a driver for SMSC's LAN911x and LAN921x families of embedded
ethernet controllers.

There is an existing smc911x driver in the tree; this is intended to
replace it.  Dustin McIntire (the author of the smc911x driver) has
expressed his support for switching to this driver.

This driver contains workarounds for all known hardware issues, and has
been tested on all flavours of the chip on multiple architectures.

This driver now uses phylib, so this patch also adds support for the
device's internal phy
