Suppressing Link Layer address in RA

I have been googling around to see if there is a way to suppress the
link layer address in RA messages when I configure my Linux box as a
router. In other words I am trying to find the equivalent of this
command :-

And so far I have been unsuccessful. The Linux IPv6 how-to too does not
mention this and Quagga seems to have a way to suppress RA, but NOT the
link layer address ( with the command "ipv6 nd suppress-ra" ). Does
anyone know if this can be accomplished in Linux and if so how ?

Thanks,
K
