Subject: [PATCH nf-next 0/2] netfilter: nf_tables: use NLA_POLICY_MASK instead of manual checks

nf_tables still uses manual attribute validation in multiple places.
Make NLA_POLICY_MASK available with NLA_BE16/NLA_BE32 and then start
using it for flag attribute validation.

Florian Westphal (2):
  netlink: allow be16 and be32 types in all uint policy checks
  netfilter: nf_tables: use NLA_POLICY_MASK to test for valid flag
    options
