[Backport: commit 90ca51e8c654699b672ba61aeaa418dfb3252e5e]
This backport to avoid the bug caused by r8169.
This effectively reverts 4b5f82f6aaef. On a number of systems ASPM L1
causes tx timeouts with RTL8168h, see referenced bug report.
Fixes: 4b5f82f6aaef ("r8169: enable ASPM L1/L1.1 from RTL8168h")
Cc: [email protected]
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217814
