+Statistics exported via /proc/net/stat - Added in 2.6.9
+======================================================================
+(C) 2004 by Harald Welte <laforge@gnumonks.org>
+
+/proc/net/stat is a generalized replacement for /proc/net/rt_cache_stat.
+
+In addition to routing cache statistics, it supports any kind of statistics
+the linux kernel exports via a file in /proc/net/stat.  In a stock 2.6.9
+kernel, this is 
+	per-protocol neighbour cache statistics 
+		(ipv4, ipv6, atm, decnet)
+	routing cache statistics
+		(ipv4)
+	connection tracking statistics
+		(ipv4)
+
+
+In order to get a convenient reading of those statistics, a tool called
+'lnstat' is provided at http://svn.gnumonks.org/trunk/lnstat
+
+This tool is to be integrated in the next release of the iproute2 program.
+
+
+If you want to add your own kernel statistics to /proc/net/stat, the file has
+to have the following properties:
+
+0) Field seperator is always one or two spaces.  No tabs, etc.
+
+1) First line consists out of a template of field names.  This is usually the
+   structure member names of the statistics structure you want to dump
+
+2) All following lines consists of unsigned hexadecimal values. One line per
+   available CPU.  Only as many fields as specified in template line.
+
+3) Please test if it works with the 'lnstat' tool before submitting a patch
+   to the kernel.
+
+Any questions should be directed to netdev@lists.oss.sgi.com or to the author
+of this document.
