Subject: [PATCH] [IPROUTE2] Compatibility with iptables 1.4.0

Hi, probably like this will be better?
Previous patch was not backward compatible.

Btw i checked twice, name is changed from libipt_MARK to libxt_MARK. So
probably when you have tested this, your iproute2 was looking to old
libipt_MARK (iptables is not deleting old libraries on make install).

-------------------------

New iptables 1.4.0 need additional dummy functions, and some library names is
changed from libipt to libxt.
It is prefferable also to open libxt_ first, as newer "style".
