Merge branch 'ethtool-track-custom-rss-contexts-in-the-core'

Edward Cree says:

====================
ethtool: track custom RSS contexts in the core

Make the core responsible for tracking the set of custom RSS contexts,
 their IDs, indirection tables, hash keys, and hash functions; this
 lets us get rid of duplicative code in drivers, and will allow us to
 support netlink dumps later.

This series only moves the sfc EF10 & EF100 driver over to the new API;
 other drivers (mvpp2, octeontx2, mlx5, sfc/siena, bnxt_en) can be converted
 afterwards and the legacy API removed.
