[PATCH net-next v3 0/3] r8169: Implement dynamic ASPM mechanism for recent 1.0/2.5Gbps Realtek NICs

[Kai-Heng Feng]

The latest Realtek vendor driver and its Windows driver implements a
feature called "dynamic ASPM" which can improve performance on it's
ethernet NICs.

Heiner Kallweit pointed out the potential root cause can be that the
buffer is to small for its ASPM exit latency.

So bring the dynamic ASPM to r8169 so we can have both nice performance
and powersaving at the same time.
