2adc55c959 e1000e: specify max supported frame size in adapter struct
By putting the maximum frame size supported by the hardware into the
adapter structure, the change_mtu entry point function can be cleaned
up of checks for all the different max frame sizes supported by

75eb0fad56 e1000e: ESB2 config after link up
On ESB2, the MAC-to-PHY (Kumeran) interface must be configured after link
is up before any traffic is sent; a new PHY operations function pointer is
provided for this.  To facilitate read/write of the Kumeran registers
without blocking PHY register writes, the driver/firmware synchronization
method which previously used a hardware semaphore for both PHY and Kumeran
register accesses is now split.  New Kumeran register read/write functions
utilize this new synchronization method.

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.

7c25769f88 e1000e: cleanup several stats issues
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.

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.
