net: marvell: prestera: Add ethtool interface support (a97d3c69) · Commits · 戴 / test

The ethtool API provides support for the configuration of the following features: speed and duplex, auto-negotiation, MDI-x, forward error correction, port media type. The API also provides information about the port status, hardware and software statistic. The following limitation exists: - port media type should be configured before speed setting - ethtool -m option is not supported - ethtool -p option is not supported - ethtool -r option is supported for RJ45 port only - the following combination of parameters is not supported: ethtool -s sw1pX port XX autoneg on - forward error correction feature is supported only on SFP ports, 10G speed - auto-negotiation and MDI-x features are not supported on Copper-to-Fiber SFP module Co-developed-by:
