mtu issue with pppoe

trying to send a pppoe packet that exceed 1422 bytes WITH no fragmentation set "on" to google.com or even any public website using the well known "icmp" ping protocol the packet wont go knowing that 20 bytes are reserved for ip, 8 bytes for the ping and 8 bytes for pppoe header >> which leaves 1464 bytes !!

Am I missing something here ?
