2cf0dbed27 SMSC: timeout reaches -1
With a postfix decrement timeouts will reach -1 rather than 0, so
the error path does not appear.

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.

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.

e81259b4f7 smsc911x: register isr as IRQF_SHARED
The isr supports shared operation, so register it with the IRQF_SHARED
flag to indicate this.

This patch also removes the IRQF_DISABLED flag.  This driver doesn't
need it, and IRQF_DISABLED isn't guaranteed when using shared interrupts.

61307ed85d smsc911x: add support for platform-specific irq flags
this patch adds support for the platform_device's resources to indicate
additional flags to use when registering the irq, for example
IORESOURCE_IRQ_LOWLEVEL (which corresponds to IRQF_TRIGGER_LOW).  These
should be set in the irq resource flags field.

1373c0fdbc smsc911x: leave RX_STOP interrupt permanently enabled
smsc911x_set_multicast_list currently performs the only non-atomic
read-modify-write of INT_EN.  This patch permanently enables the
RXSTOP_INT interrupt, and changes the ISR to only conditionally run the

288379f050 net: Remove redundant NAPI functions
Following the removal of the unused struct net_device * parameter from

bc02ff95fe net: Refactor full duplex flow control resolution
These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

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
