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

  Current release - regressions:

   - Revert "net: team: use IFF_NO_ADDRCONF flag to prevent ipv6
     addrconf", fix nsna_ping mode of team

   - wifi: mt76: fix bugs in Rx queue handling and DMA mapping

   - eth: mlx5:
      - add missing mutex_unlock in error reporter
      - protect global IPsec ASO with a lock

  Current release - new code bugs:

   - rxrpc: fix wrong error return in rxrpc_connect_call()

  Previous releases - regressions:

   - bluetooth: hci_sync: fix use of HCI_OP_LE_READ_BUFFER_SIZE_V2

   - wifi:
      - mac80211: fix crashes on Rx due to incorrect initialization of
        rx->link and rx->link_sta
      - mac80211: fix bugs in iTXQ conversion - Tx stalls, incorrect
        aggregation handling, crashes
      - brcmfmac: fix regression for Broadcom PCIe wifi devices
      - rndis_wlan: prevent buffer overflow in rndis_query_oid

   - netfilter: conntrack: handle tcp challenge acks during connection
     reuse

   - sched: avoid grafting on htb_destroy_class_offload when destroying

   - virtio-net: correctly enable callback during start_xmit, fix stalls

   - tcp: avoid the lookup process failing to get sk in ehash table

   - ipa: disable ipa interrupt during suspend

   - eth: stmmac: enable all safety features by default

  Previous releases - always broken:

   - bpf:
      - fix pointer-leak due to insufficient speculative store bypass
        mitigation (Spectre v4)
      - skip task with pid=1 in send_signal_common() to avoid a splat
      - fix BPF program ID information in BPF_AUDIT_UNLOAD as well as
        PERF_BPF_EVENT_PROG_UNLOAD events
      - fix potential deadlock in htab_lock_bucket from same bucket
        index but different map_locked index

   - bluetooth:
      - fix a buffer overflow in mgmt_mesh_add()
      - hci_qca: fix driver shutdown on closed serdev
      - ISO: fix possible circular locking dependency
      - CIS: hci_event: fix invalid wait context

   - wifi: brcmfmac: fixes for survey dump handling

   - mptcp: explicitly specify sock family at subflow creation time

   - netfilter: nft_payload: incorrect arithmetics when fetching VLAN
     header bits

   - tcp: fix rate_app_limited to default to 1

   - l2tp: close all race conditions in l2tp_tunnel_register()

   - eth: mlx5: fixes for QoS config and eswitch configuration

   - eth: enetc: avoid deadlock in enetc_tx_onestep_tstamp()

   - eth: stmmac: fix invalid call to mdiobus_get_phy()

  Misc:

   - ethtool: add netlink attr in rss get reply only if the value is not
     empty"
