Unknow packet

["Flowers, Jay" <Jay_Flowers () CHCSII COM>]

I have been experimenting with writing a sniffer in Perl.  While testing the
script I received the packet below.  The ScrMac is of my layer3 switch and I
do not know the DestMAC.  This has me worried.  I have tried Analyzer,
Ethereal, Optimal, and Tcpdump but they drop the packet for some reason
(this is an assumption; I never see the packet in their output).  Any
insight would be great.
