Blue Servo V4 network performance

Project Member Reported by haoweiw@google.com, Mar 28 2017 
Seems like the blue board is also not performing the expected network performance rate. 

I compare it with linksys USB3.0 USB ethernet adapter to transfer packet to the same devserver, chromeos6-devserver2

chromeos2-row3-rack11-host3(USB3.0 adapter):

The next step is I'm going to test is using USB3.0 adapter to the same DUT chromeos6-row1-rack2-host11 to see if it can get the good result.

Feel free to add someone who should involve this.

Long term, we may need someone from the Chrome OS kernel team
to help explain this, but let's see if the problem is the
particular ethernet driver, or broader than that.

Comment 3 by johndhong@chromium.org, Mar 28 2017 

haoweiw throw in performance to the labstation just to confirm the rack network is capable (should be as each rack in chromeos6 is 2x 1Gb)

Throwing performance to chromeos6-servov4labstation is as expected.

The conclusion is Servo V4 is not running good stage of network performance.

USB is performing at high-speed versus SuperSpeed.

The issue is due to Plugable USB hub loose power. Closing this ticket.
