[PATCH] sky2: new experimental Marvell Yukon2 driver

New driver for the Marvell Yukon2 Gigabit Ethernet chipset.
This driver is based on the skge driver, but using the logic
from the SysKonnect version of the sk98lin driver.
It should support all the Yukon2 chipsets that are available
in many current Intel and AMD motherboards.

The driver does support ethtool, tx and rx checksum, and
tcp segmentation offload.  But it has only been tested for
a short while and is known to stop receiving under heavy load.
