Subject: e1000e: fix drv load issues
From: Jesse Brandeburg <jesse.brandeburg@xxxxxxxxx>
A few people seem to have problems maintaining gigabit link and it was
root caused to an interaction between the managability firmware on the
host and the driver, not communicating.
The form of communication they use is the drv_load bit.
