Hi! This is the first (small) series which exposes some stats via the corresponding ethtool interface. Here (thanks to the excitability of netlink) we expose pause frame stats via the same interfaces as ethtool -a / -A.
In particular the following stats from the standard: - 30.3.4.2 aPAUSEMACCtrlFramesTransmitted - 30.3.4.3 aPAUSEMACCtrlFramesReceived 4 real drivers are converted, hopefully the semantics match the standard.
