* Function: tiva_ethinitialize
*
* Description:
* Initialize the Ethernet driver for one interface. If the Tiva/Stellaris
* chip supports multiple Ethernet controllers, then board specific logic
* must implement up_netinitialize() and call this function to initialize
* the desired interfaces.
*
* Parameters:
* None

* Returned Value:
* OK on success; Negated errno on failure.

* Assumptions:
