/** \addtogroup gmacb_module Ethernet GMACB Driver
*@{
* Implement GEMAC PHY driver, that initialize the PHY to prepare for
* Ethernet transfer.
*
* \section Usage
* -# EMAC related pins and Driver should be initialized at first.
* -# Initialize GMACB Driver instance by invoking GMACB_Init().
* -# Initialize PHY connected via GMACB_InitPhy(), PHY address is
* automatically adjusted by attempt to read.
* -# Perform PHY auto negotiate through GMACB_AutoNegotiate(), so
* connection established.
