Here is the call graph for this function:

int EmacOutput	(	NUTDEVICE *	dev,
		NETBUF *	nb
	)

Send Ethernet packet.

Todo:: This routine does not work.

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.

Here is the call graph for this function:

int EmacInit ( NUTDEVICE * dev )

Initialize Ethernet hardware.

Applications should do not directly call this function. It is automatically executed during during device registration by NutRegisterDevice().

Parameters:

dev	Identifies the device to initialize.

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.
