Pull networking fixes from Paolo Abeni:
 "Notably this includes fixes for a few regressions spotted very
  recently. No known outstanding ones.

  Current release - regressions:

   - core: avoid CFI problems with sock priv helpers

   - xsk: bring back busy polling support

   - netpoll: ensure skb_pool list is always initialized

  Current release - new code bugs:

   - core: make page_pool_ref_netmem work with net iovs

   - ipv4: route: fix drop reason being overridden in
     ip_route_input_slow

   - udp: make rehash4 independent in udp_lib_rehash()

  Previous releases - regressions:

   - bpf: fix bpf_sk_select_reuseport() memory leak

   - openvswitch: fix lockup on tx to unregistering netdev with carrier

   - mptcp: be sure to send ack when mptcp-level window re-opens

   - eth:
      - bnxt: always recalculate features after XDP clearing, fix
        null-deref
      - mlx5: fix sub-function add port error handling
      - fec: handle page_pool_dev_alloc_pages error

  Previous releases - always broken:

   - vsock: some fixes due to transport de-assignment

   - eth:
      - ice: fix E825 initialization
      - mlx5e: fix inversion dependency warning while enabling IPsec
        tunnel
      - gtp: destroy device along with udp socket's netns dismantle.
      - xilinx: axienet: Fix IRQ coalescing packet count overflow"
