+Subject: [PATCH 13/46] e1000e: Remove special case for 82573/82574 ASPM L1
+ disablement
+
+commit 59aed95263bdd0e2b48eb9be5a94346d2d4abf90 upstream.
+
+For the 82573, ASPM L1 gets disabled wholesale so this special-case code
+is not required. For the 82574 the previous patch does the same as for
+the 82573, disabling L1 on the adapter. Thus, this code is no longer
+required and can be removed.
