From 586d5a8bcede47fda7bebf4b36be917c5010db16 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 28 May 2021 12:30:03 +0200 Subject: netfilter: x_tables: reduce xt_action_param by 8 byte The fragment offset in ipv4/ipv6 is a 16bit field, so use u16 instead of unsigned int. On 64bit: 40 bytes to 32 bytes. By extension this also reduces nft_pktinfo (56 to 48 byte).
