 We want the ability to have scapy start sniffing on the selected interface
 when the test starts and have it stop when the test has finished.

 The problem is that the scapy sniff() call in the stable version does not
 have an easy way of telling it when it should stop sniffing.

 There is a patch for sniff() to allow the termination of sniff() based on
 the return value of a function:
