 * 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.
 *
 * Assumptions:

/****************************************************************************
 * 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:
