The orig_autoc variable tracks the original setting of the autonegotiate
state prior to trying a new speed. The usage is inconsistent and not very
maintainable. This patch updates the usage to make it more consistent.

When PHY operations are determined, the PHY must be identified. This
identification causes bus access, and should be contained within its own
routines. This also helps the 82599 PHY init paths for both SFP+ and
KX/KX4 devices to be easier to maintain.

82598's PCI bus reporting on driver load was broken after 82599 merged.
This results in incorrect reporting, and an erroneous warning message

The current code has some flaws in it when performing autonegotiation,

the autonegotiation states on link setup. The patch also removes a redundant

the ->open() path.

This patch adds support for SFP+ PHY in the following device ID's (10DB,
10F1, 10E1). These SFP+ PHY's are accessed via an I2C interface so the
patch also includes functions to support this.
Another feature of note is that the PHY is pluggable and some
rearchitecting was needed to support this.

While cleaning up the internal API focussing on Fiber and CX4 code
we found that I had broken the copper PHY initialization code. This
patch restores the PHY-specific code. This is mostly uninteresting
since no copper PHY boards are yet available. The changes have been
tested against Fiber only as I do not even have copper PHY versions
of 82598 macs.
This change actually cleans up the API code a bit more and we
lose some initialization code. A few PHY link detection helper
lines of code have been snuck into this patch, as well as a
read flush where it was suspected that this might cause issues.

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
