Merge tag 'net-6.13-rc4' 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: try the outer netns attribute in rtnl_get_peer_net()

   - rust: net::phy fix module autoloading

  Current release - new code bugs:

   - phy: avoid undefined behavior in *_led_polarity_set()

   - eth: octeontx2-pf: fix netdev memory leak in rvu_rep_create()

  Previous releases - regressions:

   - smc: check sndbuf_space again after NOSPACE flag is set in smc_poll

   - ipvs: fix clamp() of ip_vs_conn_tab on small memory systems

   - dsa: restore dsa_software_vlan_untag() ability to operate on
     VLAN-untagged traffic

   - eth:
       - tun: fix tun_napi_alloc_frags()
       - ionic: no double destroy workqueue
       - idpf: trigger SW interrupt when exiting wb_on_itr mode
       - rswitch: rework ts tags management
       - team: fix feature exposure when no ports are present

  Previous releases - always broken:

   - core: fix repeated netlink messages in queue dump

   - mdiobus: fix an OF node reference leak

   - smc: check iparea_offset and ipv6_prefixes_cnt when receiving
     proposal msg

   - can: fix missed interrupts with m_can_pci

   - eth: oa_tc6: fix infinite loop error when tx credits becomes 0"
