Current release - regressions:
 
  - bpf: fix crash due to out of bounds access into reg2btf_ids
 
  - mvpp2: always set port pcs ops, avoid null-deref
 
  - eth: marvell: fix driver load from initrd
 
  - eth: intel: revert "Fix reset bw limit when DCB enabled with 1 TC"
 
 Current release - new code bugs:
 
  - mptcp: fix race in overlapping signal events
 
 Previous releases - regressions:
 
  - xen-netback: revert hotplug-status changes causing devices to
    not be configured
 
  - dsa:
    - avoid call to __dev_set_promiscuity() while rtnl_mutex isn't held
    - fix panic when removing unoffloaded port from bridge
 
  - dsa: microchip: fix bridging with more than two member ports
 
 Previous releases - always broken:
 
  - bpf:

     and timer are present in a single value
   - fix a bpf_timer initialization issue with clang
   - do not try bpf_msg_push_data with len 0
