Merge tag 'net-6.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
"Current release - regressions:

   - tcp: fix tcp_disordered_ack() vs usec TS resolution

  Current release - new code bugs:

   - dpll: sanitize possible null pointer dereference in
     dpll_pin_parent_pin_set()

   - eth: octeon_ep: initialise control mbox tasks before using APIs

  Previous releases - regressions:

   - io_uring/af_unix: disable sending io_uring over sockets

   - eth: mlx5e:
       - TC, don't offload post action rule if not supported
       - fix possible deadlock on mlx5e_tx_timeout_work

   - eth: iavf: fix iavf_shutdown to call iavf_remove instead iavf_close

   - eth: bnxt_en: fix skb recycling logic in bnxt_deliver_skb()

   - eth: ena: fix DMA syncing in XDP path when SWIOTLB is on

   - eth: team: fix use-after-free when an option instance allocation
     fails

  Previous releases - always broken:

   - neighbour: don't let neigh_forced_gc() disable preemption for long

   - net: prevent mss overflow in skb_segment()

   - ipv6: support reporting otherwise unknown prefix flags in
     RTM_NEWPREFIX

   - tcp: remove acked SYN flag from packet in the transmit queue
     correctly

   - eth: octeontx2-af:
       - fix a use-after-free in rvu_nix_register_reporters
       - fix promisc mcam entry action

   - eth: dwmac-loongson: make sure MDIO is initialized before use

   - eth: atlantic: fix double free in ring reinit logic"
