Verify the dummy interface actually has the modified characteristics 10 # instead of relying on ifconfig output 11 # 2. Introduce more error cases, to verify ifconfig fails gracefully 12 # 3. Do more complex calls to ifconfig, while mixing the order of the 13 # arguments 14 # 4. Cover more ifconfig options: 15 # hw ether|infiniband ADDRESS - set LAN hardware address (AA:BB:CC...) 16 # txqueuelen LEN - number of buffered packets before output blocks 17 # Obsolete fields included for historical purposes: 18 #
