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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
