Thanks, I have used your method to set the MTU to 8000, but big issues rise
up
(1) Ping with msgsize>1476 will not work.
(2) Ping with msgsize<=1476 works, but the latency become longer.
(3) Netperf testing can not be executed. Even if I kill the netperf
process, status of socket created by netperf still remains "ESTABLIBSHED", I
think "FIN" packet have not been sent out successfully by each other.

Thanks,
Zhihui
