Merge tag 'net-6.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Current release - regressions:

   - rtnetlink: fix double call of rtnl_link_get_net_ifla()

   - tcp: populate XPS related fields of timewait sockets

   - ethtool: fix access to uninitialized fields in set RXNFC command

   - selinux: use sk_to_full_sk() in selinux_ip_output()

  Current release - new code bugs:

   - net: make napi_hash_lock irq safe

   - eth:
      - bnxt_en: support header page pool in queue API
      - ice: fix NULL pointer dereference in switchdev

  Previous releases - regressions:

   - core: fix icmp host relookup triggering ip_rt_bug

   - ipv6:
      - avoid possible NULL deref in modify_prefix_route()
      - release expired exception dst cached in socket

   - smc: fix LGR and link use-after-free issue

   - hsr: avoid potential out-of-bound access in fill_frame_info()

   - can: hi311x: fix potential use-after-free

   - eth: ice: fix VLAN pruning in switchdev mode

  Previous releases - always broken:

   - netfilter:
      - ipset: hold module reference while requesting a module
      - nft_inner: incorrect percpu area handling under softirq

   - can: j1939: fix skb reference counting

   - eth:
      - mlxsw: use correct key block on Spectrum-4
      - mlx5: fix memory leak in mlx5hws_definer_calc_layout"
