include/nuttx/net/netdev.h and several Ethernet drivers in arch/: Most network drivers to not support statistics. Those that do only support them when DEBUG is enabled. Each driver collects an architecture specific set of statistics and there is no mechanism in place to view those statistics. Thus, the driver feature was mostly useless. This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics.

-  Title:       STANDARDIZE ETHERNET DRIVER STATISTICS
-  Description: Need to standardize collection of statistics from network
-               drivers.  Currently they are useless because they are not
-               accessible.  The solution is to standardize the structure
-               that holds the drivers statistics.  Then apps/nshlib
-               ifconfig command could present the driver statistics.

-               Currently these drivers support non-standard statistics:
