Does it match the prefix lifetime advertised in the RA's ?

Was the Broadcom interface bridged from the start or did you bridge it
after it lost its IPv6 global address in order to run the virtual
machine ? Bridged interfaces on the host cannot receive RA's, only the
bridge interface can, unless special ebtables rules are installed.

This means that something has changed since the interface was first
brought up.
