Edit networkconfig.h so that the driver is configured with just two receive and transmit descriptors.
Compile and run the netdemo program.
Verify that the program operates properly and that you can still telnet to both the ports.
Display the driver statistics (Console `s' command or telnet `control-G' character) and verify that:
1. The number of transmit interrupts is non-zero. This indicates that all transmit descriptors have been in use at some time.
2. The number of missed packets is non-zero. This indicates that all receive descriptors have been in use at some time.
