commit ce14e691e8091187993bceccbc4740eae0821dee Author: Nikola Ciprich <[email protected]> Date: Mon Aug 20 18:46:20 2012 +0200
backport of d4a4206ebbaf48b55803a7eb34e330530d83a889 for 3.0:
e1000e: Disable ASPM L1 on 82574
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.
