The nat extension only holds information needed by pptp and the masquerade target (and in the latter case its not essential), so no need to attach it by default. First two patches add the nat extension in masquerade and pptp case, 3rd patch gets rid of the default-add. This saves 8 bytes in the extension blob unless a connection is subject to MASQERUADE and/or pptp nat helper. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
