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.

Several stats registers are completely unused and we just waste pci
bus time reading them. We also omit using the high 32 bits of the GORC/
GOTC counters. We can just read clear them and only read the low registers.
Mii-tool can also break es2lan if it executes a MII PHY register
ioctl while the device is in autonegotiation. Unfortunately it seems
that several applications and installations still perform this ioctl
call periodically and especially in this crucial startup time. We
can fool the ioctl by providing fail safe information that mimics
the "down" link state and only perform the dangerous PHY reads once
after link comes up to fill in the real values. As long as link
stays up the information will not change.

With multiple queues coming into the code these base control
registers need to be made into arrays.

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.

e1000e will from now on support the PCI-Express adapters that
previously were supported by e1000. This support means better
performance and easier debugging from now on for both the old
PCI-X/PCI hardware and PCI-Express adapters.
This patch also moves 3 recently merged device IDs over to e1000e
that are identical to quad-port versions of already existing
dual port versions. With this last bit every former e1000 pci-e
device should work now with e1000e.
Here is a brief list of which gigabit driver to use with which
adapter:
e1000:
82540 -> 82547
e1000e:
82571 -> 82573
ich8, ich9 (82562 or 82566)
es2lan (80003eslan)
igb: (not yet merged, only available from e1000.sf.net)
82575

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.
