Function Documentation

u_short NicPhyRead (  u_char  reg  )

Read contents of internel PHY register on 0x10 adress. Returns: Contents of the specified register.

void NicPhyWrite (  u_char  reg, u_short  val )

Write value to PHY register. Note: NIC interrupts must have been disabled before calling this routine. Parameters: reg  PHY register number. val  Value to write.

int AsixOutput (  NUTDEVICE *  dev, NETBUF *  nb )

Send Ethernet packet. Parameters: dev  Identifies the device to use. nb  Network buffer structure containing the packet to be sent. The structure must have been allocated by a previous call NutNetBufAlloc(). Returns: 0 on success, -1 in case of any errors.

int AsixInit (  NUTDEVICE *  dev  )

Initialize Ethernet hardware. Resets the Asix Asix_L Ethernet controller, initializes all required hardware registers and starts a background thread for incoming Ethernet traffic. Applications should do not directly call this function. It is automatically executed during during device registration by NutRegisterDevice(). If the network configuration hasn't been set by the application before registering the specified device, this function will call NutNetLoadConfig() to get the MAC address. Parameters: dev  Identifies the device to initialize.

Variable Documentation

NUTDEVICE devAx88796

Initial value: { 0, {'e', 't', 'h', '0', 0, 0, 0, 0, 0}, IFTYP_NET, 0, 0, &ifn_eth0, &dcb_eth0, AsixInit, 0, 0, 0, 0, 0, 0 } Device information structure. A pointer to this structure must be passed to NutRegisterDevice() to bind this Ethernet device driver to the Nut/OS kernel. An application may then call NutNetIfConfig() with the name eth0 of this driver to initialize the network interface.
