PPPOE Manage
When the port is configured as PPPOE Only, the port will only transmit
the PPPOE packets. But when the packet is a management one, users
could configure PPPOE Manage to 1
PPPOE Only port even if it is not a PPPOE packet. Samurai-6M/6MX
(ADM6996M/MX) identifies packets with Ether-Type = 8863
the PPPOE packet.
