-- Purpose:
-- Traffic measurment feature test implementation
-- Traffic measurment feature test implementation.
--
-- Test sequence is like so:
-- 1. Generate random number N from 0 to 5
-- 2. Measure TX counter of node 1 and RX counter of node 2
-- 3. Send N random frames
-- 4. Measure TX counter of node 1 and RX counter of node 2 again
-- 5. Compare if both counters were increased by N
