i) Fixes a bug where e1000_sw_lcd_config_ich8lan() was calling
e1000_lan_init_done_ich8lan() to poll the STATUS.LAN_INIT_DONE bit to
make sure the MAC had completed the PHY configuration. However,
e1000_lan_init_done_ich8lan() had already been called in one of the two
places where PHY reset occurs for ICHx/PCHx parts, which caused the second
call to busy-wait for 150 msec because the LAN_INIT_DONE bit had already
been checked and cleared.
ii) Cleanup the two separate PHY reset code paths, i.e. the full-chip reset
in e1000_reset_hw_ich8lan() and the PHY-only reset in
e1000_phy_hw_reset_ich8lan(). There was duplicate code in both paths to be
performed post-reset that are now combined into one new function -
e1000_post_phy_reset_ich8lan(). This cleanup also included moving the
clearing of the PHY Reset Asserted bit in the STATUS register (now done for
all ICH/PCH parts) and the check for the indication from h/w that basic
configuration has completed back to where it previously was in
e1000_get_cfg_done_ich8lan().
iii) Corrected a few comments

The mac->arc_subsystem was being incorrectly used to flag whether or not
manageability was enabled when it should only be used to state whether the
ARC (Host interface) subsystem is available on a particular MAC _and_ only
valid when any manageability is enabled. The ARC subsystem is currently
only available on 80003es2lan and 82573 parts supported by the driver.
A new flag, has_fwsm, is introduced to be used when checking if
manageability is enabled but only on parts that acutally have an FWSM
register. While the above parts have an FWSM register, there are other
parts that have FWSM but do not have support for the ARC subsystem,
namely 82571/2 and ICHx/PCH.
And then there are parts that have manageability, but do not have either
FWSM register or support for the ARC subsystem - these are 82574 and 82583.
For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no
functional changes, it only corrects the usage of the manageability flags.
For 82574 and 82583, it fixes the incorrect accesses of the non-existent
FWSM register and ARC subsystem as well as corrects the check for
management pass-through.

The force_speed_duplex function pointer was incorrectly set. Instead of
calling the 82577-specific version it was calling the m88 version which,
among other incorrect things, reset the PHY causing autonegotiation to be
re-enabled in the PHY resulting in the link defaulting to half-duplex.
The 82577-specific force_speed_duplex function also had an issue where
it disabled Auto-MDI-X which caused the link to not come up.

After every reset all ICH/PCH parts call this function which acquires the
swflag, performs a workaround on applicable parts and releases the swflag.
There is no reason for parts for which this workaround is not applicable
to acquire and release the swflag so the function should just return
without doing anything for these parts. This also provides for the
indentation of most of the function contents to be shifted left cleaning up
the code.

In MSI-X mode when an IMPI SoL session was active (i.e. the PHY reset was
blocked), the LSC interrupt generated by s/w to start the watchdog which
started the transmitter was not getting fired by the hardware because bit
24 (the 'other' cause bit) also needed to be set. Without an active SoL
session, the PHY was reset which caused the h/w to fire the LSC interrupt.

When running ethtool online diagnostics with no open interface, there is a
short period of time where the driver relinquishes control of the adapter
during which time AMT (manageability firmware) can put the adapter into an
unknown state resulting in such things as link test failure, hardware hang,
reporting an incorrect link speed, etc. Resetting the adapter during an
open() resolves this by putting the adapter into a quiescent state.

As the processor may not consider GUEST_INTR_STATE_STI as a reason for
blocking NMI, it could return immediately with EXIT_REASON_NMI_WINDOW

can run into an endless loop.
Resolve this by allowing NMI injection if just GUEST_INTR_STATE_STI is
active (originally suggested by Gleb). Intel confirmed that this is
safe, the processor will never complain about NMI injection in this
