Test passed

This test will explicitly initiate the version negotiation process by setting the Initial packet version to 0x1a2a3a4a. It will record the version negotiation advertised by the host if any. If a Version Negotiation packet is received, other Initial will be sent to check the Unused fields received to be random.
