Hi Thomas,

Information like advertising: speed, pause, autonegotiation etc. and that same for link partner advertising.

I try to mimic ethtool since it's a common, well known and widely used tool so adding an API which provides the same set of information in case the interface is passthrough to dpdk will be useful I think.

I've 2 more patches dependent on the one we are discussing now, but I need patchwork id to add dependency information. I need moderator approval for the current patch.

Regards,

Marek

Which information is missing exactly?
Why are you trying to mimic ethtool API?

Please let's add what is missing instead of adding a full new API.
