e1000e: reset PHY after errors detected

Browse source

Some errors can be induced in the PHY via environmental testing
(specifically extreme temperature changes and electro static
discharge testing), and in the case of the PHY hanging due to
this input, this detects the problem and resets to continue.
This issue only applies to 82574 silicon.
