REPARTITION NETWORK DRIVER FUNCTIONALITY

```
Description: Every network driver performs the first level of packet decoding.
It examines the packet header and calls ipv4_input(), ipv6_input().
icmp_input(), etc. as appropriate. This is a maintenance problem
because it means that any changes to the network input interfaces
affects all drivers.

A better, more maintainable solution would use a single net_input()
function that would receive all incoming packets. This function
would then perform that common packet decoding logic that is
currently implemented in every network driver.
Status: Open
Priority: Low. Really just as aesthetic maintainability issue.
