Does your device support jumbo frames or what is the largest packet size it supports?

The Maximum MSDU size supported by the MoCA technology is 1522 bytes for VLAN-tagged frames and 1518 bytes for untagged frames.  Jumbo frames are used on local area networks that support at least 1 Gbps and can be as large as 9,000 bytes. But they are not supported on our MoCA devices.
