Hi Richard,
Below is the outputs of the commands. The current ethtool version doesn't
support -T option so I have to compile version 3.7 and run for the source
directory. Thanks for your help!

This sounds like a driver bug. Can you give the output of the following
commands?
uname -a
ethtool -T eth0
testptp -g
Thanks,
Richard
