Currently I suspect the IPv6 ethernet frames are being blocked

I've encountered the situation where ND wouldn't work before on
Extreme multilayer switches, which implement(ed?) IGMP snooping such
that multicasts aren't forwarded without IGMP, even if those are non-
IPv4 multicasts that by definition can't have corresponding IGMP
messages. So see if you can get IGMP snooping disabled, or set up some
static ND entries and see if unicast IPv6 traffic makes it through.
