Merge tag 'net-5.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Current release - regressions:

   - dsa: bcm_sf2: fix array overrun in bcm_sf2_num_active_ports()

  Previous releases - regressions:

   - introduce a shutdown method to mdio device drivers, and make DSA
     switch drivers compatible with masters disappearing on shutdown;
     preventing infinite reference wait

   - fix issues in mdiobus users related to ->shutdown vs ->remove

   - virtio-net: fix pages leaking when building skb in big mode

   - xen-netback: correct success/error reporting for the
     SKB-with-fraglist

   - dsa: tear down devlink port regions when tearing down the devlink
     port on error

   - nexthop: fix division by zero while replacing a resilient group

   - hns3: check queue, vf, vlan ids range before using

  Previous releases - always broken:

   - napi: fix race against netpoll causing NAPI getting stuck

   - mlx4_en: ensure link operstate is updated even if link comes up
     before netdev registration

   - bnxt_en: fix TX timeout when TX ring size is set to the smallest

   - enetc: fix illegal access when reading affinity_hint; prevent oops
     on sysfs access

   - mtk_eth_soc: avoid creating duplicate offload entries

  Misc:

   - core: correct the sock::sk_lock.owned lockdep annotations"
