From 66fc2862a252f7356e7aa5eeb44519ee005fd066 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 10 Jun 2021 22:56:59 +0200 Subject: [PATCH] r8169: avoid link-up interrupt issue on RTL8106e if user enables ASPM [ Upstream commit 1ee8856de82faec9bc8bd0f2308a7f27e30ba207 ] It has been reported that on RTL8106e the link-up interrupt may be significantly delayed if the user enables ASPM L1. Per default ASPM is disabled. The change leaves L1 enabled on the PCIe link (thus still allowing to reach higher package power saving states), but the NIC won't actively trigger it.
