| * 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 |
| * "canonically 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. |

| * Function: sam_phy_boardinitialize |

| * Description: |

| * the PHY, etc. If CONFIG_SAMV7_EMAC0_PHYINIT or |
| * CONFIG_SAMV7_EMAC1_PHYINIT is defined in the configuration then the |
| * board specific logic must provide sam_phyinitialize(); |
