Merge tag 'net-6.2-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from can and ipsec subtrees.

  Current release - regressions:

   - sched: fix off by one in htb_activate_prios()

   - eth: mana: fix accessing freed irq affinity_hint

   - eth: ice: fix out-of-bounds KASAN warning in virtchnl

  Current release - new code bugs:

   - eth: mtk_eth_soc: enable special tag when any MAC uses DSA

  Previous releases - always broken:

   - core: fix sk->sk_txrehash default

   - neigh: make sure used and confirmed times are valid

   - mptcp: be careful on subflow status propagation on errors

   - xfrm: prevent potential spectre v1 gadget in xfrm_xlate32_attr()

   - phylink: move phy_device_free() to correctly release phy device

   - eth: mlx5:
      - fix crash unsetting rx-vlan-filter in switchdev mode
      - fix hang on firmware reset
      - serialize module cleanup with reload and remove"
