Pull networking fixes from Jakub Kicinski:
 "Including fixes from BPF and big collection of fixes for WiFi core and
  drivers.

  Current release - regressions:

   - vxlan: fix regression when dropping packets due to invalid src
     addresses

   - bpf: fix a potential use-after-free in bpf_link_free()

   - xdp: revert support for redirect to any xsk socket bound to the
     same UMEM as it can result in a corruption

   - virtio_net:
      - add missing lock protection when reading return code from
        control_buf
      - fix false-positive lockdep splat in DIM
      - Revert "wifi: wilc1000: convert list management to RCU"

   - wifi: ath11k: fix error path in ath11k_pcic_ext_irq_config

  Previous releases - regressions:

   - rtnetlink: make the "split" NLM_DONE handling generic, restore the
     old behavior for two cases where we started coalescing those
     messages with normal messages, breaking sloppily-coded userspace

   - wifi:
      - cfg80211: validate HE operation element parsing
      - cfg80211: fix 6 GHz scan request building
      - mt76: mt7615: add missing chanctx ops
      - ath11k: move power type check to ASSOC stage, fix connecting to
        6 GHz AP
      - ath11k: fix WCN6750 firmware crash caused by 17 num_vdevs
      - rtlwifi: ignore IEEE80211_CONF_CHANGE_RETRY_LIMITS
      - iwlwifi: mvm: fix a crash on 7265

  Previous releases - always broken:

   - ncsi: prevent multi-threaded channel probing, a spec violation

   - vmxnet3: disable rx data ring on dma allocation failure

   - ethtool: init tsinfo stats if requested, prevent unintentionally
     reporting all-zero stats on devices which don't implement any

   - dst_cache: fix possible races in less common IPv6 features

   - tcp: auth: don't consider TCP_CLOSE to be in TCP_AO_ESTABLISHED

   - ax25: fix two refcounting bugs

   - eth: ionic: fix kernel panic in XDP_TX action

  Misc:

   - tcp: count CLOSE-WAIT sockets for TCP_MIB_CURRESTAB"

In this case, it is possible to use the NIC's packet steering
capabilities to steer the packets to the right queue. This is not
possible in the previous example as there is only one queue shared
among sockets, so the NIC cannot do this steering as it can only steer
between queues.
There is no need to supply an XDP program like the one in the previous
case where sockets were bound to the same queue id and
device. Instead, use the NIC's packet steering capabilities to steer
the packets to the right queue. In the previous example, there is only
one queue shared among sockets, so the NIC cannot do this steering. It
can only steer between queues.
In libxdp (or libbpf prior to version 1.0), you need to use the
xsk_socket__create_shared() API as it takes a reference to a FILL ring
and a COMPLETION ring that will be created for you and bound to the
shared UMEM. You can use this function for all the sockets you create,
or you can use it for the second and following ones and use
xsk_socket__create() for the first one. Both methods yield the same
result.
