- 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.
