netfilter: nf_tables: kill nft_pktinfo.ops
- Add nft_pktinfo.pf to replace ops->pf - Add nft_pktinfo.hook to replace ops->hooknum This simplifies the code, makes it more readable, and likely reduces cache line misses. Maintainability is enhanced as the details of nft_hook_ops are of no concern to the recpients of nft_pktinfo. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
