4.4: Driver basic operation

The network demonstration program netdemo may be used for these tests.

Edit networkconfig.h to reflect the values for your network.
Start with RTEMS_USE_BOOTP not defined.
Edit networkconfig.h to configure the driver with an explicit Ethernet and Internet address and with reception of broadcast packets disabled:
Verify that the program continues to run once the driver has been attached.
Issue a `u' command to send UDP packets to the `discard' port. Verify that the packets appear on the network.
Issue a `s' command to print the network and driver statistics.
On a workstation, add a static route to the target system.
On that same workstation try to `ping' the target system. Verify that the ICMP echo request and reply packets appear on the net.
Remove the static route to the target system. Modify networkconfig.h to attach the driver with reception of broadcast packets enabled. Try to `ping' the target system again. Verify that ARP request/reply and ICMP echo request/reply packets appear on the net.
Issue a `t' command to send TCP packets to the `discard' port. Verify that the packets appear on the network.
Issue a `s' command to print the network and driver statistics.
Verify that you can telnet to ports 24742 and 24743 on the target system from one or more workstations on your network.
