The Match app compares packets received on its input port rx with those
received on the reference input port comparator, and reports mismatches as
well as packets from comparator that were not matched.

— Method Match:errors
Returns the recorded errors as an array of strings.
The Match app accepts a table as its configuration argument. The following
keys are defined:
— Key fuzzy
Optional. If this key is true packets from rx that do not match the next
packet from comparator are ignored. The default is false.
— Key modest
Optional. If this key is true unmatched packets from comparator are
ignored if at least one packet from ´rx´ was successfully matched. The default
is false.
The Synth app generates synthetic packets with Ethernet headers and
alternating payload sizes. On each breath it fills each attached output link
with new packets.

The Synth app accepts a table as its configuration argument. The following
keys are defined:
— Key src
— Key dst
Source and destination MAC addresses in human readable from. The default is
"00:00:00:00:00:00".
— Key sizes
An array of numbers designating the packet payload sizes. The default is
{64}.
— Key random_payload
Generate a random payload for each packet in sizes
— Key packet_id Insert the packet number (32bit uint) directly after the ethertype. The packet number starts at 0 and is sequential on each output link.
The Npackets app allows are most N packets to flow through it. Any further
packets are never dequeued from input.

The Npackets app accepts a table as its configuration argument. The following
keys are defined:
— Key npackets The number of packets to forward, further packets are never dequeued from input.
