Merge tag 'net-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Quite smaller than usual. Notably it includes the fix for the unix
  regression from the past weeks. The TCP window fix will require some
  follow-up, already queued.

  Current release - regressions:

   - af_unix: fix garbage collection of embryos

  Previous releases - regressions:

   - af_unix: fix race between GC and receive path

   - ipv6: sr: fix missing sk_buff release in seg6_input_core

   - tcp: remove 64 KByte limit for initial tp->rcv_wnd value

   - eth: r8169: fix rx hangup

   - eth: lan966x: remove ptp traps in case the ptp is not enabled

   - eth: ixgbe: fix link breakage vs cisco switches

   - eth: ice: prevent ethtool from corrupting the channels

  Previous releases - always broken:

   - openvswitch: set the skbuff pkt_type for proper pmtud support

   - tcp: Fix shift-out-of-bounds in dctcp_update_alpha()

  Misc:

   - a bunch of selftests stabilization patches"
