2020-03-15nft_set_pipapo: Prepare for single ranged field usageStefano Brivio
A few adjustments in nft_pipapo_init() are needed to allow usage of this set back-end for a single, ranged field. Provide a convenient NFT_PIPAPO_MIN_FIELDS definition that currently makes sure that the rbtree back-end is selected instead, for sets with a single field. This finally allows a fair comparison with rbtree sets, by defining NFT_PIPAPO_MIN_FIELDS as 0 and skipping rbtree back-end initialisation: ---------------.--------------------------.-------------------------.

2020-03-15nft_set_pipapo: Prepare for vectorised implementation: helpersStefano Brivio
Move most macros and helpers to a header file, so that they can be conveniently used by related implementations. No functional changes are intended here. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
