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

  Current release - regressions:

   - bpf: synchronize dispatcher update with bpf_dispatcher_xdp_func

   - rxrpc:
      - fix security setting propagation
      - fix null-deref in rxrpc_unuse_local()
      - fix switched parameters in peer tracing

  Current release - new code bugs:

   - rxrpc:
      - fix I/O thread startup getting skipped
      - fix locking issues in rxrpc_put_peer_locked()
      - fix I/O thread stop
      - fix uninitialised variable in rxperf server
      - fix the return value of rxrpc_new_incoming_call()

   - microchip: vcap: fix initialization of value and mask

   - nfp: fix unaligned io read of capabilities word

  Previous releases - regressions:

   - stop in-kernel socket users from corrupting socket's task_frag

   - stream: purge sk_error_queue in sk_stream_kill_queues()

   - openvswitch: fix flow lookup to use unmasked key

   - dsa: mv88e6xxx: avoid reg_lock deadlock in mv88e6xxx_setup_port()

   - devlink:
      - hold region lock when flushing snapshots
      - protect devlink dump by the instance lock

  Previous releases - always broken:

   - bpf:
      - prevent leak of lsm program after failed attach
      - resolve fext program type when checking map compatibility

   - skbuff: account for tail adjustment during pull operations

   - macsec: fix net device access prior to holding a lock

   - bonding: switch back when high prio link up

   - netfilter: flowtable: really fix NAT IPv6 offload

   - enetc: avoid buffer leaks on xdp_do_redirect() failure

   - unix: fix race in SOCK_SEQPACKET's unix_dgram_sendmsg()

   - dsa: microchip: remove IRQF_TRIGGER_FALLING in
     request_threaded_irq"
