The phy resets are what we do in the phy-exynos5-usbdrd driver. In
addition to what we
have currently in this phy driver, we just need the phy calibration
patch [1] for phy configurations.

This shows the ethernet device gets detected on the high-speed port of one
of the controller.
The lsusb output for kernel v4.7.x posted by Michael show that the
ethernet device got detected on super-speed port of the controller.
So, there seems to be a difference between the two.
Or, is this how it is behaving ?
Is this lsusb output on 4.8 kernel with the patch [1] ?

If i understand, below is how the configuration looks like on the board?
+-----------------------+
+------>| |
| | Bus 6 |-------+
+-----------+ | (super-speed) | |
| | +-----------------------+ |
|Controller | | --------> Ethernet device
| 2 | |
| | +-----------------------+ |
+-----------+ | | |
| | Bus 5 |-------+
+------>| (high-speed) |
+-----------------------+
+-----------------------+
+------>| |
| | Bus 4 |-------+
+-----------+ | (super-speed) | |
| | +-----------------------+ |
|Controller | | --------> (On board
hub ?? _OR_ external hub with downstream devices) ???
| 1 | |
| | +-----------------------+ |
+-----------+ | | |
| | Bus 3 |-------+
+------>| (high-speed) |
+-----------------------+
Thanks
