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

  Current release - regressions:

   - revert "net: fix cpu_max_bits_warn() usage in
     netif_attrmask_next{,_and}"

   - revert "net: sched: fq_codel: remove redundant resource cleanup in
     fq_codel_init()"

   - dsa: uninitialized variable in dsa_slave_netdevice_event()

   - eth: sunhme: uninitialized variable in happy_meal_init()

  Current release - new code bugs:

   - eth: octeontx2: fix resource not freed after malloc

  Previous releases - regressions:

   - sched: fix return value of qdisc ingress handling on success

   - sched: fix race condition in qdisc_graft()

   - udp: update reuse->has_conns under reuseport_lock.

   - tls: strp: make sure the TCP skbs do not have overlapping data

   - hsr: avoid possible NULL deref in skb_clone()

   - tipc: fix an information leak in tipc_topsrv_kern_subscr

   - phylink: add mac_managed_pm in phylink_config structure

   - eth: i40e: fix DMA mappings leak

   - eth: hyperv: fix a RX-path warning

   - eth: mtk: fix memory leaks

  Previous releases - always broken:

   - sched: cake: fix null pointer access issue when cake_init() fails"
