ixgbe: driver for Intel(R) 82598 PCI-Express 10GbE adapters (v4)

This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.

This version of the driver is largely the same as the last release:

  * Driver uses a single RX and single TX queue, each using 1 MSI-X
  irq vector.
  * Driver runs in NAPI mode only
  * Driver is largely multiqueue-ready (TM)

Changes since 20070803:
  * removed wrappers for hardware functions
  * incorporated e1000e-style HW api reorganization code
  * sparse/checkpatch cleanups, namespace cleanups
  * driver prints out extra debugging information at load time
    identifying adapter board number, mac, phy types
  * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
  * driver update to 1.1.18
  * removed ixgbe.txt which contained no useful info anymore
