From fa538f7cf05aab61cd91e01c160d4a09c81b8ffe Mon Sep 17 00:00:00 2001 From: "Jose M. Guisado Gomez" Date: Thu, 22 Oct 2020 21:43:51 +0200 Subject: netfilter: nf_reject: add reject skbuff creation helpers Adds reject skbuff creation helper functions to ipv4/6 nf_reject infrastructure. Use these functions for reject verdict in bridge family. Can be reused by all different families that support reject and will not inject the reject packet through ip local out. Signed-off-by: Jose M.

It means the set may consume more memory but gives faster evaluation at matching in the set.
