igb: PCI-Express 82575 Gigabit Ethernet driver

We are pleased to announce a new Gigabit Ethernet product and its
driver to the linux community. This product is the Intel(R) 82575
Gigabit Ethernet adapter family. Physical adapters will be available
to the public soon. These adapters come in 2- and 4-port versions
(copper PHY) currently. Other variants will be available later.

The 82575 chipset supports significantly different features that
warrant a new driver. The descriptor format is (just like the
ixgbe driver) different. The device can use multiple MSI-X vectors
and multiple queues for both send and receive. This allows us to
optimize some of the driver code specifically as well compared to
the e1000-supported devices.

This version of the igb driver no lnger uses fake netdevices and
incorporates napi_struct members for each ring to do the multi-
queue polling. multi-queue is enabled by default and the driver
supports NAPI mode only.

All the namespace collisions should be gone in this version too. The
register macro's have been condensed to improve readability.
