97ac8caee2 e1000e: Add support for BM PHYs on ICH9
This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.

This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).

To make code read a bit easier we introduce a _IS_ICH flag so
that we don't need to do mac type checks over the code.

2d9498f369 e1000e: Fix HW Error on es2lan, ARP capture issue by BMC
Several components to this complex fix. The es2lan cards occasionally
gave a "HW Error" especially when forcing speed. Some users also
reported that the BMC stole ARP packets.

The fixes include setting the proper SW_FW bits to tell the BMC
that we're active and not do any un-initialization at all, so the
setup routine is largely changed.

318a94d689 e1000e: reorganize PHY and flow control interface
This reorganization moves the PHY status into a separate
struct. Flow Control setup is moved into this struct as well
and frame size away from here into the adapter struct where its
inly use is.

The post-link-up code is now a separate function and moved out
of the watchdog function itself. This allows us to track the
es2lan restart issue a bit easier.

bc7f75fa97 [E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)
This driver implements support for the ICH9 on-board LAN ethernet
device. The device is similar to ICH8.

The driver encompasses code to support 82571/2/3, es2lan and ICH8
devices as well, but those device IDs are disabled and will be
"lifted" from the e1000 driver over one at a time once this driver
receives some more live time.

Changes to the last snapshot posted are exclusively in the internal
hardware API organization. Many thanks to Jeff Garzik for jumping in
and getting this organized with a keen eye on the future layout.
