----------------------------------------+-----------------------------------
 Currently the function capturePackets in ooni/utils/net.py defers to a
 thread the scapy sniff() function.

 This is not ideal since we have ooni/utils/txscapy.py that is made for
 using the scapy super socket file descriptor in a non-blocking way.

 the capturePackets function should be refactored to use ScapyProtocol in
 ooni/utils/txscapy.py
