Merge tag 'net-5.19-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from can.

  Still no major regressions, most of the changes are still due to data
  races fixes, plus the usual bunch of drivers fixes.

  Previous releases - regressions:

   - tcp/udp: make early_demux back namespacified.

   - dsa: fix issues with vlan_filtering_is_global

  Previous releases - always broken:

   - ip: fix data-races around ipv4_net_table (round 2, 3 & 4)

   - amt: fix validation and synchronization bugs

   - can: fix detection of mcp251863

   - eth: iavf: fix handling of dummy receive descriptors

   - eth: lan966x: fix issues with MAC table

   - eth: stmmac: dwmac-mediatek: fix clock issue

  Misc:

   - dsa: update documentation"
