Pull networking fixes from Paolo Abeni:
 "Including fixes from bpf, ipsec and netfilter.

  No solution yet for the stmmac issue mentioned in the last PR, but it
  proved to be a lockdep false positive, not a blocker.

  Current release - regressions:

   - dpll: move all dpll<>netdev helpers to dpll code, fix build
     regression with old compilers

  Current release - new code bugs:

   - page_pool: fix netlink dump stop/resume

  Previous releases - regressions:

   - bpf: fix verifier to check bpf_func_state->callback_depth when
     pruning states as otherwise unsafe programs could get accepted

   - ipv6: avoid possible UAF in ip6_route_mpath_notify()

   - ice: reconfig host after changing MSI-X on VF

   - mlx5:
       - e-switch, change flow rule destination checking
       - add a memory barrier to prevent a possible null-ptr-deref
       - switch to using _bh variant of of spinlock where needed

  Previous releases - always broken:

   - netfilter: nf_conntrack_h323: add protection for bmp length out of
     range

   - bpf: fix to zero-initialise xdp_rxq_info struct before running XDP
     program in CPU map which led to random xdp_md fields

   - xfrm: fix UDP encapsulation in TX packet offload

   - netrom: fix data-races around sysctls

   - ice:
       - fix potential NULL pointer dereference in ice_bridge_setlink()
       - fix uninitialized dplls mutex usage

   - igc: avoid returning frame twice in XDP_REDIRECT

   - i40e: disable NAPI right after disabling irqs when handling
     xsk_pool

   - geneve: make sure to pull inner header in geneve_rx()

   - sparx5: fix use after free inside sparx5_del_mact_entry

   - dsa: microchip: fix register write order in ksz8_ind_write8()

  Misc:

   - selftests: mptcp: fixes for diag.sh"
