This is the batch 1 of patches touching netdev for preparing for
the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by to structs that would
benefit from the annotation.

Since the element count member must be set before accessing the annotated
flexible array member, some patches also move the member's initialization
earlier. (These are noted in the individual patches.)

Hi, just checking on this batch of changes. Is it possible to take the
1-13 subset:

Kees Cook (14):
  ipv4: Annotate struct fib_info with __counted_by
  ipv4/igmp: Annotate struct ip_sf_socklist with __counted_by
  ipv6: Annotate struct ip6_sf_socklist with __counted_by
  net: hns: Annotate struct ppe_common_cb with __counted_by
  net: enetc: Annotate struct enetc_int_vector with __counted_by
  net: hisilicon: Annotate struct rcb_common_cb with __counted_by
  net: mana: Annotate struct mana_rxq with __counted_by
  net: ipa: Annotate struct ipa_power with __counted_by
  net: mana: Annotate struct hwc_dma_buf with __counted_by
  net: openvswitch: Annotate struct dp_meter_instance with __counted_by
  net: enetc: Annotate struct enetc_psfp_gate with __counted_by
  net: openvswitch: Annotate struct dp_meter with __counted_by
  net: tulip: Annotate struct mediatable with __counted_by

I'll respin 14 and add it to the next batch:

  net: sched: Annotate struct tc_pedit with __counted_by

After these 13, there are  32 more patches to various drivers and
protocols...

Thanks!
