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
