#
# Usage: testing.exp <path to arping> <ifname> <ip address> <mac address>
#
# Test all cases against a "normal" machine:
# * Responds to ARP
# * Responds to ping
# * Doesn't respond to broadcast pings.
#
# Abnormal machines, to be tested elsewhere:
# * Proxy ARP
# * Respond to broadcast pings
# * Lost packets
# * Duplicated replies
#
# Tested here:
# * -a
# * -c
# * -d (minimally)
# * -D
# * -e
# * -h
# * -q (soon)
# * -r
# * -R
# * -s (soon)
# * -S (soon)
# * -t
# * -T
# * -u (soon)
# * -v (soon)
# * -w (soon)
# * -W (soon)
#
# Not tested here:
# * -0
# * -A (forced on with mac ping)
# * -b
# * -B
# * -p
# * -P
# * -U
# * -V
# * Mac ping without -T.
