Description Andrew Lunn 2002-04-22 08:07:03 EDT

Description of Problem:

The TCP/IP stack declares a structure tcp_debug. This is used for debugging tcp
using a user space program. The structure currently contains space for 100
connections. Each connection requires 264 bytes of memory. So the total
structure is consuming 25Kbytes of memory. 

I think its very unlikly anyone will use this facility, can i suggest the table
is shruck down to 1 or 2 entries? You need to modify
packages/net/tcpip/current/include/netinet/tcp_debug.h:121
