Duplicate MACs in seastat

Why are the MAC addresses duplicated in the "seastat" command output for all the LPARs? I can't figure out why one stanza has the LPAR information (hostname and IP) while the other stanza does not? Why the two separate sections and two separate sets of usage information (Bytes and Packets)?

Maybe it sees it on two NICs? No, only one IP report, IP and non-IP Ethernet packets? Per client with one client? IBM
