I have recently bought a Keenetic KN-1910 Skipper, but it seems that it lacks RFC4638 support. I set 1500 MTU on the PPPoE connection but a DF ping still shows max MTU of 1492. For RFC4638 support, the ethernet interface would need an MTU of at least 1510 bytes, since it needs to transport packet payload + VLAN tag (802.1q - 2byte) and PPPoE header (6+2=8bytes).
My ISP supports RFC4638 and it uses VLAN + PPPoE. Under a different router running OpenWRT, I can set MTU of 1510 and have this working.
Would it be possible to add this feature into the next KeeneticOS release, or is there a way to achieve the same permanently (into saved settings) via CLI?
