Wireshark receives the all the packets which are forwarded from NIC card to processor.
NIC card discards the packets only if destination address is not matched.
From the above packet I understood that the Destination address is "FFFFFFFFFFFF", which is a broadcast packet and NIC card wont drop this kind of packets.
In any case whether the filed is "0000" or "8000" it doesnt matter.
R u setting any filtering options in wireshark?
