TP-Link TD-W8980 and SMP

Hello, I am wondering about the current state of SMP on this Lantiq VR9 based platform. Question comes up because some more power would be very nice for SQM QoS working without making the single used core glow in the darkness. Any news here? I heard of quite some patches for OpenWRT to fix problems with it. Are these still up to date for LEDE or included already?

SMP on vr9 is possible in general, but then the VPE (voice process engine ?) will not support, it need by Telephony.
