< triple_speed_ethernet_iniche.h > Include:
The triple_speed ethernet_init() function opens and initializes the Triple-
Speed Ethernet driver. Initialization involves the following operations:
• Set up the NET structure of the MAC device instance.
• Configure the MAC PHY Address.
• Register and open the SGDMA RX and TX Module of the MAC device instance.
• Enable the SGDMA RX interrupt and register it to the Operating System.
• Register the SGDMA RX callback function.
• Obtains the PHY Speed of the MAC.
• Set up the Ethernet MAC Register settings for the Triple-Speed Ethernet driver
operation.
• Set up the initial descriptor chain to start the SGDMA RX operation.
Description:
p_dev
—A pointer to the Triple-Speed Ethernet device instance. Parameter:
SUCCESS
if the Triple-Speed Ethernet driver is successfully initialized. Return:
