+<p>This patch can solve your problems if you have network connection dropping too much
+packets. In standard case the Linux kernel will correctly increase our round-trip-time
+of connection slowing the transfer rate up to the unusable state.</p>
+<p>After applying this patch you can set your maximal round-trip-time in file
+&quot;<b>/proc/sys/net/ipv4/tcp_rto_max</b>&quot;, it is expressed in <tt>Hz</tt>
+units (<tt>100-per-second</tt> on <i>x86</i> platform). You may need also to enlarge
+your maximal retry count in &quot;<b>/proc/sys/net/ipv4/tcp_retries2</b>&quot;,
+otherwise <u>your</u> machine will reject the connection as it will have to retry
+the packets more than in sane states.</p>
+<p><font color="red">Please use this feature very carefully! You are violating
+<tt>RFC</tt> standards and you can get your network administrators to be very angry!</font></p>
