From: Chris Boot <[email protected]> commit id 59aed95263bdd0e2b48eb9be5a94346d2d4abf90 Backport to 3.2-3.4 kernels
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.
