Pull networking fixes from Jakub Kicinski:
 "Including fixes from bluetooth, and ipsec.

  Current release - regressions:

   - Bluetooth: fix unbalanced unlock in set_device_flags()

   - Bluetooth: fix not processing all entries on cmd_sync_work, make
     connect with qualcomm and intel adapters reliable

   - Revert "xfrm: state and policy should fail if XFRMA_IF_ID 0"

   - xdp: xdp_mem_allocator can be NULL in trace_mem_connect()

   - eth: ice: fix race condition and deadlock during interface enslave

  Current release - new code bugs:

   - tipc: fix incorrect order of state message data sanity check

  Previous releases - regressions:

   - esp: fix possible buffer overflow in ESP transformation

   - dsa: unlock the rtnl_mutex when dsa_master_setup() fails

   - phy: meson-gxl: fix interrupt handling in forced mode

   - smsc95xx: ignore -ENODEV errors when device is unplugged

  Previous releases - always broken:

   - xfrm: fix tunnel mode fragmentation behavior

   - esp: fix inter address family tunneling on GSO

   - tipc: fix null-deref due to race when enabling bearer

   - sctp: fix kernel-infoleak for SCTP sockets

   - eth: macb: fix lost RX packet wakeup race in NAPI receive

   - eth: intel stop disabling VFs due to PF error responses

   - eth: bcmgenet: don't claim WOL when its not available"
