Merge tag 'net-5.16-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf, can and netfilter.

  Current release - regressions:

   - bpf, sockmap: re-evaluate proto ops when psock is removed from
     sockmap

  Current release - new code bugs:

   - bpf: fix bpf_check_mod_kfunc_call for built-in modules

   - ice: fixes for TC classifier offloads

   - vrf: don't run conntrack on vrf with !dflt qdisc

  Previous releases - regressions:

   - bpf: fix the off-by-two error in range markings

   - seg6: fix the iif in the IPv6 socket control block

   - devlink: fix netns refcount leak in devlink_nl_cmd_reload()

   - dsa: mv88e6xxx: fix "don't use PHY_DETECT on internal PHY's"

   - dsa: mv88e6xxx: allow use of PHYs on CPU and DSA ports

  Previous releases - always broken:

   - ethtool: do not perform operations on net devices being
     unregistered

   - udp: use datalen to cap max gso segments

   - ice: fix races in stats collection

   - fec: only clear interrupt of handling queue in fec_enet_rx_queue()

   - m_can: pci: fix incorrect reference clock rate

   - m_can: disable and ignore ELO interrupt

   - mvpp2: fix XDP rx queues registering

  Misc:

   - treewide: add missing includes masked by cgroup -> bpf.h
     dependency"
