JIRA: https://issues.redhat.com/browse/RHEL-150155

Backport a number of core networking lock changes, namely:

  • Conversion of RTNL sections to RCU.
  • Removal of the RTNL lock in favor of dedicated ones.
  • Per-netns RTNL & related changes (e.g. smaller RTNL sections). This will be
    disabled in RHEL.

The over ideas are 1) to make other backports easier 2) improve RTNL section
performances.

Some pre-requisites are included. Some related patches have already been
backported and merged (e.g. per-netdev locks).

Omitted-fix: 34f71de3f548 ("net: avoid false positive warnings in __net_mp_close_rxq()"). This is unrelated to this MR and is providing an additional fix, not fixing the referenced commit. Not backporting it won't introduce a regression.

Omitted-fix: cbada1048847 ("neighbour: restore protocol != 0 check in pneigh update"). This is a non-critical fix and we'll backport the fix in a follow-up MR during this cycle.
