4 # Brief: Some cursery coverage tests of ifconfig...
5 # Note: requires permissions to run modprobe and all ifconfig options
6 # Commands used: grep, grep -i, ip link, ip tuntap, wc -l
8 # Possible improvements:
9 # 1. 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
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 # irq|io_addr|mem_start ADDR - micromanage obsolete hardware
19 # outfill|keepalive INTEGER - SLIP analog dialup line quality monitoring
20 # metric INTEGER - added to Linux 0.9.10 with comment "never used", still true
