+-- Purpose:
+--  Stuff bit on last bit of Data field.
+--
+-- Verifies:
+--  1. When stuff bit is inserted after last bit of Data field, no extra stuff
+--     bit will be inserted during first bit of Stuff count (with fixed
+--     stuffing). Wait until frame is sent. Read frame and check it is received
+--     succesfully!
+--
+--  Test sequence:
+--  1. Generate CAN frame which has last 5 bits of data field dominant! Send
+--     it by Node 1. Wait until frame is sent and read it from Node 2. Check
+--     that frames are equal.
+--     Note: The check is only visual so far...
