>Description:

	Currently 32 bits variables are used to collect tcp statistics.
	With some network load (6 GB/day outgoing HTTP traffic/day),
	the number of tcp bytes transferred as shown by netstat becomes
	negative after 8 hours uptime.

>How-To-Repeat:

	Run netstat -s on a machine that has been up with some network
	load for some time.

>Fix:
	Use 64 bits integers for some of the numbers, e.g. packet 
	and byte counters, and modify netstat to use %qd instead of %ld
        in the corresponding format argument to printf.
