[dts] [PATCH V1] tests/shutdown_api: add the sagepond speed/duplex status in change_linkspeed

[wenjieli]

It is NOT a DPDK issue.
With sagepond nic on DUT, after change DUT nic speed/duplex by linux commands
"ethtool -s ethX speed SPEED duplex full", the tester nic speed and duplex 
will change to "Unknown" and disconnec from its peer port. 
"Unknown" is expected behavior, and will not check packet forwarding.
