ltq-RFC4638 PPPoE MTU support

I have a TP-Link TDW8970, used with VDSL.
It seems to limit me to a PPP MTU of 1492. I need to increase the MTU on the ptm0 device to 1508 AIUI but it won’t let me. Could it be as simple as providing our own ptm_change_mtu() will will tolerate a larger MTU, instead of using eth_change_mtu()?
