Subject: [RFC PATCH v3 net-next 0/7] ethtool: track custom RSS contexts in the core
Date: Tue, 12 Sep 2023 15:21:35 +0100 [thread overview]
Message-ID: <cover.1694443665.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 v3:
* Added WangXun ngbe to patch #1, not sure if they've added WoL support since
v2 or if I just missed it last time around
* Re-ordered struct ethtool_netdev_state to avoid hole (Andrew Lunn)
* Fixed some resource leaks in error handling paths (kuba)
* Added maintainers of other context-using drivers to CC
Edward Cree (7):
net: move ethtool-related netdev state into its own struct
net: ethtool: attach an IDR of custom RSS contexts to a netdevice
net: ethtool: record custom RSS contexts in the IDR
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
