[Feat]: network interface hardware statistics about netdata HOT 1 OPEN

There is nice and complex feat

As far as I know it is only possible to monitor these hw statistics using ethtool, but there is probably an interface that could be used directly.

The kernel interfaces is ethtool & ethtool_netlink

Have there been any attempts to add this to netdata? Yes, for example #14674

The implementation of fields from the driver requires a special approach to normalize the metrics. That is, what you presented for Mellanox will not work for Intel. And it won't work for virtio, at least. To solve this the plugin need at least a parser, a good example of implementation that I can give is a project ethq where the parser determines from the driver name what it needs to look for (example)

Currently netdata don't have any part of ethtool interface, but if this interface will be available, there will be another parts that's may be covered:

• info about real interface max speed, see #14803
• SFP transceiver info, see project https://github.com/wobcom/transceiver-exporter (it uses ethtool -m <iface>, from userland, actually)

What this implementation gives to netdata product - expansion of equipment on which netdata will be indispensable! 'White boxes' - the Ethernet Switches with linux as control-plane, for example Edge-Core will be added to servers and virtual machines

from netdata.
