[RFC PATCH v3 7/8] net: sparx5: add ethtool configuration and statistics support
Steen Hegelund

Fri Jan 15 08:53:38 EST 2021
This adds statistic counters for the network interfaces provided
by the driver. It also adds CPU port counters (which are not
exposed by ethtool).
This also adds support for configuring the network interface
parameters via ethtool: speed, duplex, aneg etc.
