The arping test transmits a single packet and immediately tries to pull
the log for upcall details. This works fine in practice on most systems
but can fail under a slower VM where it can take a while for the log
data to be written. By adding addtional transmits we give the system
time to write, and also increase the opportunity to not miss processing
the upcall queue.
