Description (partial)

7800 and 8800 phone to support jumbo frames

Transmission of frames greater than 1500 bytes drops or not transmitted by phone to PC if connected to the phone.
 If DF bit is not set the frames will be broken up and still transmitted in smaller packets to the device connected on the PC port. The packets are not passed through the port if they are true jumbo packets.

In the vast majority of networks this is not going to be an issue.
