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
