Raja-san,

Thanks for your response.

I would like to use Ethernet with checksum offload disable.

First, I disabled Packet Accellerator. But, ethernet also could not be used.
Actually I modified Kernel config like following:
# "make menuconfig"
Device Drivers --> Network device support --> Ethernet driver support --> [N] TI Keystone Packet Accelerator Support

Next, I tried to disable by "ethtool" as follows, but it is also not effected:
# ethtool -K eth0 tx off rx off

Best regards, RY

ethtool --show-offload  eth0

ethtool --offload  eth0  rx off  tx off

ethtool -K eth0 gso off

ethtool --show-offload  eth0
