Subject: nfp: link basic ethtool ops to representors
Patch-mainline: v4.14-rc1
Git-commit: 06726f30364c38f12519e2c6c046f19b2aa509bc
References: bsc#1055968

Start linking ethtool ops to representors.  Begin by adding
a separate ops structure and providing link state.  Next
patches will convert appropriate functions to only use nfp_port,
which will make them reusable on representors.
