No...at a Cisco IPv6 meeting over a year ago (I'm pretty sure you were 
there too) Mr IPv6 in Cisco said sorry the WLC 4400[1] is effectively 
dire and cannot do IPv6 filtering.  I then asked about MAC filtering to 
do exactly as you are wanting...and they said...nope.

As far as I know the WLC 5500 runs effectively the same codebase, well 
thats what the Cisco sales rep confessed to and gives you nothing better 
than the 4400.

'Great'

Like us over at SOAS, you too will have to stare at all that IPv6 
multicast traffic floating around, knowing that you cannot do anything 
about it... :(

I would love to be wrong on this, so please someone correct me...

Cheers

[1] my understanding is that the WiSM ~= WLC
