* 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 arm_netinitialize() and call this function to initialize the
* desired interfaces.
*
* Input 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.
*
* Input Parameters:
* intf - Always zero for now.
*
* Returned Value:
* OK on success; Negated errno on failure.
*
* Assumptions:
