      - fix kernel BUG in purge_effective_progs()
   - mac80211:
      - fix possible leak in ieee80211_tx_control_port()
      - potential NULL dereference in ieee80211_tx_control_port()
  Current release - new code bugs:
   - nfp: fix the access to management firmware hanging
  Previous releases - regressions:
   - ip: fix triggering of 'icmp redirect'
   - sched: tbf: don't call qdisc_put() while holding tree lock
   - bpf: fix corrupted packets for XDP_SHARED_UMEM
   - bluetooth: hci_sync: fix suspend performance regression
   - micrel: fix probe failure
  Previous releases - always broken:
   - tcp: make global challenge ack rate limitation per net-ns and
     default disabled
