Downloaded 1.8.4 pre-built just a few days ago from wireshark.org.

My trace included some FCoE packets with a destination address of
01:10:18:01:00:01.  This is reserved as the FCoE Etherner Group Multicast MAC
Address for ALL_ENODE_MACS.  It displayed as Broadcom_01:00:01.  If the
Organizationally Unique Identifier (OUI) had been 00:10:18, this would be
correct, but 01:10:18 is reserved as an FCoE group identifier.

See packet 185 in the attachment for an example.  Note that there are several
other reserved multicast addresses in this same range.
