Merge tag 'net-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Current release - regressions:

   - nvme-tcp: fix comma-related oops after sendpage changes

  Current release - new code bugs:

   - ptp: make max_phase_adjustment sysfs device attribute invisible
     when not supported

  Previous releases - regressions:

   - sctp: fix potential deadlock on &net->sctp.addr_wq_lock

   - mptcp:
      - ensure subflow is unhashed before cleaning the backlog
      - do not rely on implicit state check in mptcp_listen()

  Previous releases - always broken:

   - net: fix net_dev_start_xmit trace event vs skb_transport_offset()

   - Bluetooth:
      - fix use-bdaddr-property quirk
      - L2CAP: fix multiple UaFs
      - ISO: use hci_sync for setting CIG parameters
      - hci_event: fix Set CIG Parameters error status handling
      - hci_event: fix parsing of CIS Established Event
      - MGMT: fix marking SCAN_RSP as not connectable

   - wireguard: queuing: use saner cpu selection wrapping

   - sched: act_ipt: various bug fixes for iptables <> TC interactions

   - sched: act_pedit: add size check for TCA_PEDIT_PARMS_EX

   - dsa: fixes for receiving PTP packets with 8021q and sja1105 tagging

   - eth: sfc: fix null-deref in devlink port without MAE access

   - eth: ibmvnic: do not reset dql stats on NON_FATAL err

  Misc:

   - xsk: honor SO_BINDTODEVICE on bind"
