It's very possible the MAC address is the problem, since it is a
multicast Ethernet address (the low order bit of the first octet
is set).  If you are defining your own MAC address, you should set
the locally defined bit (second lowest order bit of the first octet),
and not set the multicast bit (e.g. use "12" instead of "11" for the
first octet).
