Merge tag 'net-6.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Current release - regressions:

   - wifi: mt76: mt7915: add back 160MHz channel width support for
     MT7915

   - libbpf: revert poisoning of strlcpy, it broke uClibc-ng

  Current release - new code bugs:

   - bpf: improve the coverage of the "allow reads from uninit stack"
     feature to fix verification complexity problems

   - eth: am65-cpts: reset PPS genf adj settings on enable

  Previous releases - regressions:

   - wifi: mac80211: serialize ieee80211_handle_wake_tx_queue()

   - wifi: mt76: do not run mt76_unregister_device() on unregistered hw,
     fix null-deref

   - Bluetooth: btqcomsmd: fix command timeout after setting BD address

   - eth: igb: revert rtnl_lock() that causes a deadlock

   - dsa: mscc: ocelot: fix device specific statistics

  Previous releases - always broken:

   - xsk: add missing overflow check in xdp_umem_reg()

   - wifi: mac80211:
      - fix QoS on mesh interfaces
      - fix mesh path discovery based on unicast packets

   - Bluetooth:
      - ISO: fix timestamped HCI ISO data packet parsing
      - remove "Power-on" check from Mesh feature

   - usbnet: more fixes to drivers trusting packet length

   - wifi: iwlwifi: mvm: fix mvmtxq->stopped handling

   - Bluetooth: btintel: iterate only bluetooth device ACPI entries

   - eth: iavf: fix inverted Rx hash condition leading to disabled hash

   - eth: igc: fix the validation logic for taprio's gate list

   - dsa: tag_brcm: legacy: fix daisy-chained switches

  Misc:

   - bpf: adjust insufficient default bpf_jit_limit to account for
     growth of BPF use over the last 5 years

   - xdp: bpf_xdp_metadata() use EOPNOTSUPP as unique errno indicating
     no driver support"
