[ 121/127] e1000e: Disable ASPM L1 on 82574

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Boot <bootc@xxxxxxxxx>

commit d4a4206ebbaf48b55803a7eb34e330530d83a889 upstream.

ASPM on the 82574 causes trouble. Currently the driver disables L0s for
this NIC but only disables L1 if the MTU is >1500. This patch simply
causes L1 to be disabled regardless of the MTU setting.
