Test Sequence Execution Log

23:07:06	Start
	Initialization
23:07:06	Start Capturing Packets (Link0)
	This is very tricky, but send echo-reply (src = NUT/dst = TN) to get valid checksum value.
23:07:06	vSend(Link0,echo_reply_link_local) send echo_reply_link_local
23:07:06	Clear Captured Packets (Link0)
	Test
23:07:06	vSend(Link0,echo_request) Send Echo Request (Link-local address)
23:07:06	vRecv(Link0,echo_reply ns_local ns_local_sll) timeout:5 cntLimit:0 seektime:0 Receive Echo Reply (Link-local address)
	Checksum value included in NUT's sending packet is valid OK
