From 51d8e7091033042d3ae09363abe5e93d0698930e Mon Sep 17 00:00:00 2001
From: Chris Boot <bootc@bootc.net>

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.
