Merge tag 'net-6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Current release - regressions:

   - dsa: sja1105: fix reception from VLAN-unaware bridges

   - Revert "net: stmmac: set PP_FLAG_DMA_SYNC_DEV only if XDP is
     enabled"

   - eth: fec: don't save PTP state if PTP is unsupported

  Current release - new code bugs:

   - smc: fix lack of icsk_syn_mss with IPPROTO_SMC, prevent null-deref

   - eth: airoha: update Tx CPU DMA ring idx at the end of xmit loop

   - phy: aquantia: AQR115c fix up PMA capabilities

  Previous releases - regressions:

   - tcp: 3 fixes for retrans_stamp and undo logic

  Previous releases - always broken:

   - net: do not delay dst_entries_add() in dst_release()

   - netfilter: restrict xtables extensions to families that are safe,
     syzbot found a way to combine ebtables with extensions that are
     never used by userspace tools

   - sctp: ensure sk_state is set to CLOSED if hashing fails in
     sctp_listen_start

   - mptcp: handle consistently DSS corruption, and prevent corruption
     due to large pmtu xmit"
