Merge branch 'nfp-add-basic-ethtool-callbacks-to-representors' 

Jakub Kicinski says:

====================
nfp: add basic ethtool callbacks to representors

This set extends the basic ethtool functionality to representor
netdevs.  I start with providing link state via ethtool and then
move on to functions such as driver information, statistics and
FW log dump.  The series contains a number of clean ups to the
ethtool stats code too, some of the logic is simplified by making
better use of the nfp_port abstraction.  The stats we expose on
representors are only the PCIe and MAC port statistics firmware
maintains for us.
====================
