Merge tag 'net-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from rxrpc, netfilter, wireless and bluetooth
  subtrees.

  Current release - regressions:

   - skb: export skb drop reaons to user by TRACE_DEFINE_ENUM

   - bluetooth: fix regression preventing ACL packet transmission

  Current release - new code bugs:

   - dsa: microchip: fix kernel oops on ksz8 switches

   - dsa: qca8k: fix NULL pointer dereference for
     of_device_get_match_data

  Previous releases - regressions:

   - netfilter: clean up hook list when offload flags check fails

   - wifi: mt76: fix crash in chip reset fail

   - rxrpc: fix ICMP/ICMP6 error handling

   - ice: fix DMA mappings leak

   - i40e: fix kernel crash during module removal

  Previous releases - always broken:

   - ipv6: sr: fix out-of-bounds read when setting HMAC data.

   - tcp: TX zerocopy should not sense pfmemalloc status

   - sch_sfb: don't assume the skb is still around after
     enqueueing to child

   - netfilter: drop dst references before setting

   - wifi: wilc1000: fix DMA on stack objects

   - rxrpc: fix an insufficiently large sglist in
     rxkad_verify_packet_2()

   - fec: use a spinlock to guard `fep->ptp_clk_on`

  Misc:

   - usb: qmi_wwan: add Quectel RM520N"
