Block PPPOE Requests How-To

Hi Ive got a pppoe server on mikrotik and I do want to block certain clients from connecting using their mac addresses as filter, I can not use the firewall since pppoe is a IP-Less protocol. So I do have to use some data-link layer mechanism for filtering any ideas on how to achieve that ?

Groundhog Day, again?
