The device may not support that packet length. The packet is being fragmented anyway so it is not real useful. In general you should only send packets that are maximum 1 MTU in length. This tends to be between 1400 and 1500.

If you want to find out the mtu, then put "-f" on your ping command. That is a don't fragment option.

ping -f -l 1470 8.8.8.8
