 The following APIs are available to the test case for reading pcap files.
 
-* `get_capture`: this API is suitable for bulk & batch style of test, where
-  a list of packets is prepared & sent, then the received packets are read
-  and verified. The API needs the number of packets which are expected to
-  be captured (ignoring filtered packets - see below) to know when the pcap
-  file is completely written by the VPP. If using packet infos for verifying
-  packets, then the counts of the packet infos can be automatically used
-  by `get_capture` to get the proper count (in this case the default value
-  None can be supplied as expected_count or ommitted altogether).
-* `wait_for_packet`: this API is suitable for interactive style of test,
-  e.g. when doing session management, three-way handsakes, etc. This API waits
-  for and returns a single packet, keeping the capture file in place

 Automatic filtering of packets:

-Both APIs (`get_capture` and `wait_for_packet`) by default filter the packet
-capture, removing known uninteresting packets from it - these are IPv6 Router
-Advertisments and IPv6 Router Alerts. These packets are unsolicitated
-and from the point of |vtf| are random. If a test wants to receive these
-packets, it should specify either None or a custom filtering function
-as the value to the 'filter_out_fn' argument.
