It means that IPv6 module is _not_ unloadable. You can load it once.

Autoconfiguration is supported _only_ on ethernet interfaces.
Nobody of folks having access to token ring took care of sending
a patch to calculate eui64 tokens and to map multicast addresses
for token ring.

The problem is that existing specs for IPv6 over tr are _expired_
long time ago, so that implementor have to verify against any existing
implementation.

You choosed a strange method to deconfig IPv6 interfaces.
Use ifconfig instead.

It is correct. IPv6 module cannot be unloaded.

I did not receive any patches handling token ring for last two years.
