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"
