Description (partial)

Certain scenarios such a Layer2 extension/OTV can add additional frame overhead.  The total frame size can exceed the standard 1500 MTU, causing fragmentation.
The UCSM CLI and GUI do not provide a mechanism to adjust/lower the mgmt interface MTU size.
This is needed for customers trying to join UCSM to UCS Central over OTV link.
