Description (partial)

When a m91xx/m92xx mgmt interface and its peer are configured for full duplex, the mds mgmt interface will come up in half duplex.

This happens when the counter part of the m91xx/m92xx mgmt interface connection is configured full duplex mode. 

Configure both interfaces to auto duplex achieve a full duplex connection.
