>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.
