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.
