net: ethtool: let the core choose RSS context IDs
Add a new API to create/modify/remove RSS contexts, that passes in the
newly-chosen context ID (not as a pointer) rather than leaving the
driver to choose it on create. Also pass in the ctx, allowing drivers
to easily use its private data area to store their hardware-specific
state.
Keep the existing .set_rxfh API for now as a fallback, but deprecate it
for custom contexts (rss_context != 0).
