From: Dmitry Mishin Date: Wed, 22 Mar 2006 21:56:56 +0000 (-0800) Subject: [NETFILTER]: futher {ip,ip6,arp}_tables unification X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=v2.6.16-1689-g1e30a01;p=mv-sheeva.git [NETFILTER]: futher {ip,ip6,arp}_tables unification This patch moves {ip,ip6,arp}t_entry_{match,target} definitions to x_tables.h. This move simplifies code and future compatibility fixes. Signed-off-by: Dmitry Mishin Acked-off-by: Kirill Korotaev Signed-off-by: Patrick McHardy Signed-off-by: David S.
