Merge tag 'net-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from CAN, wireless, Bluetooth, and Netfilter.

  Current release - regressions:

   - Revert "kunit: configs: Enable CONFIG_INIT_STACK_ALL_PATTERN in
     all_tests", makes kunit error out if compiler is old

   - wifi: iwlwifi: mvm: fix assert on suspend

   - rxrpc: fix return from none_validate_challenge()

  Current release - new code bugs:

   - ovpn: couple of fixes for socket cleanup and UDP-tunnel teardown

   - can: kvaser_pciefd: refine error prone echo_skb_max handling logic

   - fix net_devmem_bind_dmabuf() stub when DEVMEM not compiled

   - eth: airoha: fixes for config / accel in bridge mode

  Previous releases - regressions:

   - Bluetooth: hci_qca: move the SoC type check to the right place, fix
     GPIO integration

   - prevent a NULL deref in rtnl_create_link() after locking changes

   - fix udp gso skb_segment after pull from frag_list

   - hv_netvsc: fix potential deadlock in netvsc_vf_setxdp()

  Previous releases - always broken:

   - netfilter:
       - nf_nat: also check reverse tuple to obtain clashing entry
       - nf_set_pipapo_avx2: fix initial map fill (zeroing)

   - fix the helper for incremental update of packet checksums after
     modifying the IP address, used by ILA and BPF

   - eth:
       - stmmac: prevent div by 0 when clock rate is misconfigured
       - ice: fix Tx scheduler handling of XDP and changing queue count
       - eth: fix support for the RGMII interface when delays configured"
