At least on a proper ethernet interface we still answer NS for our addresses, even if we disable sending them. So the questions still are: Do you see those solicitatins going from the driver to the IP layer? And do you see any Neighbor Advertisement replies from the IP layer? If the respective answers are yes/no, then you should look elsewhere to find the problem. Too restrictive ip6tables maybe? If the answers are no/no or yes/yes, then we need to look closer at the driver.
