After fixing #210 this is working for me (on TP-Link WD8970 with VDSL) as long as I ask nicely for the MTU to be set on the underlying Ethernet interface — in my case "interfaces" as there's a VLAN involved:


config interface 'vdsl'
        option proto 'pppoe'
        option username 'fo'
        option password 'bar'
        option ipv6 'auto'
        option ifname 'ptm0.101'
        option mtu '1500'

config switch_vlan 'ptm0_101'
        option device 'ptm0'
        option vlan '101'
        option vid '101'

config interface 'aa101'
        option ifname 'ptm0.101'
        option proto 'none'
        option mtu '1508'
        option delegate '0'

config interface 'ptm0'
        option ifname 'ptm0'
        option proto 'none'
        option mtu '1508'
        option delegate '0'
