Subject: [PATCH v4 net-next 0/7] ethtool: track custom RSS contexts in the core
Date: Wed, 27 Sep 2023 19:13:31 +0100	[thread overview]
Message-ID: <cover.1695838185.git.ecree.xilinx@gmail.com> (raw)

From: Edward Cree <ecree.xilinx@gmail.com>

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; if
 the design is approved of, I plan to post a follow-up series to convert the
 other drivers (mvpp2, octeontx2, mlx5, sfc/siena) and remove the legacy API.
However, I don't have hardware for the drivers besides sfc, so I won't be
 able to test those myself.  Maintainers of those drivers (on CC), your
 comments on the API design would be appreciated, in particular whether the
 rss_ctx_max_id limit (corresponding to your fixed-size arrays of contexts)
 is actually needed.

Changes in v4:
* replaced IDR with XArray
* grouped initialisations together in patch 6
* dropped RFC tags

Edward Cree (7):
  net: move ethtool-related netdev state into its own struct
  net: ethtool: attach an XArray of custom RSS contexts to a netdevice
  net: ethtool: record custom RSS contexts in the XArray
  net: ethtool: let the core choose RSS context IDs
  net: ethtool: add an extack parameter to new rxfh_context APIs
  net: ethtool: add a mutex protecting RSS contexts
  sfc: use new rxfh_context API
