ALLMULTI Required for Avahi on Kilauea/Haleakala

I am working on getting avahi-daemon along with nss-mdns up and running on
an the AMCC Kilauea/Haleakala development boards and noted that in order for
other systems to discover it and vice versa, ALLMULTI has to be enabled on
'eth0'. 

Is this a known works-as-designed aspect of the IBM new_emac driver or a
TBD/WIP implementation issue in the driver?

Regards,

Grant
