Merge tag 'net-6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from can, wireless and netfilter.

  Current release - regressions:

   - af_unix: fix task hung while purging oob_skb in GC

   - pds_core: do not try to run health-thread in VF path

  Current release - new code bugs:

   - sched: act_mirred: don't zero blockid when net device is being
     deleted

  Previous releases - regressions:

   - netfilter:
      - nat: restore default DNAT behavior
      - nf_tables: fix bidirectional offload, broken when unidirectional
        offload support was added

   - openvswitch: limit the number of recursions from action sets

   - eth: i40e: do not allow untrusted VF to remove administratively set
     MAC address

  Previous releases - always broken:

   - tls: fix races and bugs in use of async crypto

   - mptcp: prevent data races on some of the main socket fields, fix
     races in fastopen handling

   - dpll: fix possible deadlock during netlink dump operation

   - dsa: lan966x: fix crash when adding interface under a lag when some
     of the ports are disabled

   - can: j1939: prevent deadlock by changing j1939_socks_lock to rwlock

  Misc:

   - a handful of fixes and reliability improvements for selftests

   - fix sysfs documentation missing net/ in paths

   - finish the work of squashing the missing MODULE_DESCRIPTION()
     warnings in networking"
