+<H2>DESCRIPTION</H2>
+
+<I>/proc/net/ipsec_tncfg</I>
+
+is a read-only file which lists which IPSEC virtual interfaces are
+attached to which real interfaces, through which packets will be
+forwarded once processed by IPSEC.
+<P>
+
+Each line lists one ipsec I/F.
+A table entry consists of:
+<DL COMPACT>
+<DT>+<DD>
+an ipsec virtual I/F name
+<DT>+<DD>
+a visual and machine parsable separator '-&gt;', separating the virtual I/F
+and the physical I/F,
+<DT>+<DD>
+a physical I/F name, to which the ipsec virtual I/F is attached or NULL
+if it is not attached,
+<DT>+<DD>
+the keyword
+<B>mtu=</B>,
+
+<DT>+<DD>
+the MTU of the ipsec virtual I/F,
+<DT>+<DD>
+the automatically adjusted effective MTU for PMTU discovery, in brackets,
+<DT>+<DD>
+a visual and machine parsable separator '-&gt;', separating the virtual I/F
+MTU and the physical I/F MTU,
+<DT>+<DD>
+the MTU of the attached physical I/F.
