Merge tag 'net-6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from WiFi and bpf.

  Current release - regressions:

   - bpf: syzkaller found null ptr deref in unix_bpf proto add

   - eth: i40e: fix ST code value for clause 45

  Previous releases - regressions:

   - core: return error from sk_stream_wait_connect() if sk_wait_event()
     fails

   - ipv6: revert remove expired routes with a separated list of routes

   - wifi rfkill:
       - set GPIO direction
       - fix crash with WED rx support enabled

   - bluetooth:
       - fix deadlock in vhci_send_frame
       - fix use-after-free in bt_sock_recvmsg

   - eth: mlx5e: fix a race in command alloc flow

   - eth: ice: fix PF with enabled XDP going no-carrier after reset

   - eth: bnxt_en: do not map packet buffers twice

  Previous releases - always broken:

   - core:
       - check vlan filter feature in vlan_vids_add_by_dev() and
         vlan_vids_del_by_dev()
       - check dev->gso_max_size in gso_features_check()

   - mptcp: fix inconsistent state on fastopen race

   - phy: skip LED triggers on PHYs on SFP modules

   - eth: mlx5e:
       - fix double free of encap_header
       - fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list()"

* tag 'net-6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (69 commits)
  net: check dev->gso_max_size in gso_features_check()
