Description (partial)

Ports on a 60x10GE LC do not forward traffic and/or remain up/up despite nothing connected to the interfaces.

4x10GE PHY loads microcode from SPI flash instead of via MDIO. The contents of each 4x10GE PHY SPI flash determines if microcode will be loaded from SPI flash or if it will be loaded via MDIO. If microcode is loaded from SPI flash, there is a chance it will fail.
This DDTS ensures that microcode is always loaded via MDIO.
