these are defined for the Linux ASPM interfaces, e.g.,
pci_disable_link_state(), and only coincidentally match the actual register

When there is heavy traffic and the cable is pulled, the driver must reset
the adapter to flush the Tx queue in hardware.  This causes the reset path
to be scheduled and logs the message "Reset adapter" which could be mis-
interpreted as an error by the user.  Change how the reset path is invoked
for this scenario by using the same method done in an existing work-around
for 80003es2lan (i.e. set a flag and if the flag is set in the reset code
do not log the "Reset adapter" message since the reset is expected).

Re-name the FLAG_RX_RESTART_NOW to FLAG_RESTART_NOW since it is used for
resets in both the Rx and Tx specific code.

Energy Efficient Ethernet on 82579 and I217 should only be enabled if not
disabled by the user, if the link is full duplex and the link partner has
similar EEE capabilities (stored in different EMI registers on the two
different parts).

After enabling EEE, read the IEEE MMD register 3.1 (which is also stored in
different EMI registers on the two different parts) to clear the count of
received Tx/Rx LPI indications.

Also, rename I217_EEE_100_SUPPORTED to I82579_EEE_100_SUPPORTED to indicate
the bit is valid starting with I82579 (released before I217).

When data blocks are written to the EEPROM, the HW/SW/FW semaphore must be
held for the duration.  With large data blocks on 80003es2lan, 82571 and
82572, this can take too long and cause the firmware to take ownership of
the semaphore and consequently ownership of writes to the EEPROM.
Instead, acquire and release the semaphore for each page of the block
written.

The X540's internal thermal sensor should not be enabled for all devices, but
only those devices which enable it in the NVM image. It is expected that
actively cooled devices will have it enabled, but passively cooled devices might
not want it enabled. This is due to passively cooled devices operating very near
the thermal threshold, sometimes within the margin of error of the thermal
sensor. Thus these devices may not be good candidates for using the thermal
sensor.

This patch uses the enabled bit in the FWSM register to check whether we should
be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag
for those devices which have it enabled.
