Merge tag 'net-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/netHEADmaster

Pull networking fixes from Jakub Kicinski:
  Previous releases - regressions:

   - netlink: avoid infinite retry looping in netlink_unicast()

  Previous releases - always broken:

   - packet: fix a race in packet_set_ring() and packet_notifier()

   - ipv6: reject malicious packets in ipv6_gso_segment()

   - sched: mqprio: fix stack out-of-bounds write in tc entry parsing

   - net: drop UFO packets (injected via virtio) in udp_rcv_segment()

   - eth: mlx5: correctly set gso_segs when LRO is used, avoid false
     positive checksum validation errors

   - netpoll: prevent hanging NAPI when netcons gets enabled

   - phy: mscc: fix parsing of unicast frames for PTP timestamping

   - a number of device tree / OF reference leak fixes"
