cmd: net: add a 'net stats' command to dump network statistics

Browse source 
Add a new option to the 'net' command which can be used to dump network
statistics.

To do this, 3 new callbacks are added to the eth_ops structure:
.get_sset_count(), .get_strings(), .get_stats(). These callbacks
have the same functions as in Linux: to return the number of counters,
the strings which describe those counters and the actual values.
