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.

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.

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.

Convert the driver to select 16-bit or 32-bit bus access at runtime,
at a small performance cost.

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
