* Function: stm32_ethinitialize
*
* Description:
* Initialize the Ethernet driver for one interface. If the STM32 chip supports
* multiple Ethernet controllers, then board specific logic must implement
* up_netinitialize() and call this function to initialize the desired interfaces.
*
* Parameters:
* intf - In the case where there are multiple EMACs, this value identifies which
* EMAC is to be initialized.
*
* Returned Value:
* OK on success; Negated errno on failure.

* Function: stm32_phy_boardinitialize
*
* Description:
* Some boards require specialized initialization of the PHY before it can be used.
* This may include such things as configuring GPIOs, resetting the PHY, etc. If
* CONFIG_STM32_PHYINIT is defined in the configuration then the board specific
* logic must provide stm32_phyinitialize(); The STM32 Ethernet driver will call
* this function one time before it first uses the PHY.
*
* Parameters:
* intf - Always zero for now.
*
* Returned Value:
* OK on success; Negated errno on failure.
*
* Assumptions:
