#
# Brief: Some cursery coverage tests of ifconfig...
# Note: requires permissions to run modprobe and all ifconfig options
# Commands used: grep, grep -i, ip link, ip tuntap, wc -l
#
# Possible improvements:
# 1. Verify the dummy interface actually has the modified characteristics
# instead of relying on ifconfig output
# 2. Introduce more error cases, to verify ifconfig fails gracefully
# 3. Do more complex calls to ifconfig, while mixing the order of the
# arguments
# 4. Cover more ifconfig options:
# hw ether|infiniband ADDRESS - set LAN hardware address (AA:BB:CC...)
# txqueuelen LEN - number of buffered packets before output blocks
# Obsolete fields included for historical purposes:
# irq|io_addr|mem_start ADDR - micromanage obsolete hardware
# outfill|keepalive INTEGER - SLIP analog dialup line quality monitoring
# metric INTEGER - added to Linux 0.9.10 with comment "never used", still true
