/****************************************************************************
* Function: sam_emac_setmacaddr
*
* Description:
* There are two ways that the Ethernet MAC address can be set:
*
* 1) Application level code can set the Ethernet MAC address using a
* netdev ioctl. The application level code have gotten the MAC
* address from some configuration parameter or by accessing some
* non-volatile storage containing the address. This is the
* "cannonically correct" way to set the MAC address.
* 2) Alterntively, the board logic may support some other less obvious
* non-volatile storage and the board-level boot-up code may access
* this and use this interface to set the Ethernet MAC address more
* directly. This is mostly a kludge for the case where you just don't
* want to expose a application level storage interface.
*
* Input Parameters:
* intf - If multiple EMAC peripherals are supported, this identifies the
* the EMAC peripheral being initialized.
*
* Returned Value:
* OK on success; Negated errno on failure.
*
* Assumptions:
* Called very early in the initialization sequence.

/************************************************************************************
* Function: sam_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_SAMV7_PHYINIT is defined in the configuration then the board specific
* logic must provide sam_phyinitialize(); The SAMV7 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:
