[PATCH] proc.txt document fix of error_burst and error_cost

[PATCH] proc.txt document fix of error_burst and error_cost

Hi,

Jamal asked me to direct this patch to you both. 

In short, the patch fixes some bad documentation of the error_burst and 
error_cost sysctl's in Documentation/filesystems/proc.txt. I have tried to 
retain the old style of the document as much as possible, as well as 
choice of words. 

The patch should apply against both 2.4.19 and 2.5.45 without problems.

Is there anything wrong with it, or may it be included? Suggestions?

 error_burst and error_cost
 --------------------------
 
-These parameters  are used to limit the warning messages written to the kernel
-log from  the  routing  code.  The  higher the error_cost factor is, the fewer
-messages will  be written. Error_burst controls when messages will be dropped.
-The default settings limit warning messages to one every five seconds.
+These  parameters  are used to limit how many ICMP destination unreachable to 
+send  from  the  host  in question. ICMP destination unreachable messages are 
+sent  when  we can not reach the next hop, while trying to transmit a packet. 
+It  will also print some error messages to kernel logs if someone is ignoring 
+our   ICMP  redirects.  The  higher  the  error_cost  factor  is,  the  fewer 
+destination  unreachable  and error messages will be let through. Error_burst 
+controls  when  destination  unreachable  messages and error messages will be
+dropped. The default settings limit warning messages to five every second.
