No ideas on how to get the link local address initialized in IPv6? Any ideas on how to add an IPv6 route so I can try adding the ff02:: multicast route manually? Is there any documentation for the eCos IPv6 APIs? It appears that even configuring an IPv4 static address is sufficient to allow IPv6 multicast packets to be sent to ff02:: /16 addresses. But IPv6 should not have to depend on IPv4 being configured. -- Grant Edwards grant.b.edwards Yow!
