Feng Pan 099ac31f8f Change ping wait flag
This is an optimization of the ping command. It changes ping test
from waiting for a single sent packet for 300 seconds to waiting
to receive a packet from any number of sent packets. The current
implemenation waits for full 300 seconds before retrying if we
do not get a reply for the first packet sent. By using -w flag,
we keep sending icmp packets until a reply is sent, making the
ping test more responsive to connectivity change.
