|
|
* 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_SAMD5E5_GMAC_PHYINIT is defined in the

|
|
* sam_phyinitialize(); The SAMD5E5 Ethernet driver will call this

|
*
|
|
* Input Parameters:
|
|
* intf - Always zero for now.
