transport: Set mtu to 9000 for all 10GbE use cases

Browse Source 
An default MTU value of 9000 gives the devices the most flexibility
using 10GbE. Many interfaces and docs have already been updated.
This is bringing all devices into alignment with this paradigm.

The default MTU for the N3x0 series is 9000. The simplest solution is often to

Of course, you can also reduce the MTU on the device to match your host
computer, see Section \ref n3xx_getting_started_connectivity.
