AM6442: AM64xx TCP/IP throughput on Gigabit line

Tool/software:

Hi Team,

My question is regarding AM64xx support for JUMBO frame for TCP/IP communication.

Here is our requirement and set-up:

Setup :

AM64xx configured for gigabit ethernet over CPSW using RGMII

Stack : FreeRTOS based LwIP provided by SDK latest.

Requirement : 

Am64xx should be able send around 650 Mbits per second to PC over TCP/IP link (Note : It is Point to Point connection using static IP)

In this regarding , I would like to understand ,

Is it possible achieve 650 Mbps throughput using standard frame size(MTU) which 1500 bytes?

if not then how change standard frame size to Jumbo frame up 9000 Bytes ?  Does AM64xx FreeRTOS based LwIP support Jumbo frames ?
