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). Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
