get_network_stats returns the network traffic stored in the kernel. E.g. |

Bugs: |

|
get_network_stats_diff on very first call will return the same as |
| 42 |
|
get_network_stats. After first call it will always return the difference. |
| 43 |
+ |
On machines that hold only 32bits of information, if the call is made 2x |
| 44 |
+ |
wrap around (eg sol7 9gb has been transferred, and it wraps at 4gb) it will |
| 45 |
+ |
return incorrect results (case above, it would say 5gb transferred). |
