typedef void(* tfNetRxCallback)(void *apBuffer, int anLen, void *apUser, bool abInIsr)

This prototype defines a callback function that is activated each time an Ethernet packet is received from the network.

Parameters:

[in]	apBuffer	Pointer to the Ethernet packet.
[in]	anLen	The number of bytes in the Ethernet packet.
[in]	apUser	A callback-specific parameter supplied when the callback is registered.
[in]	abInIsr	True if being called from ISR context

Returns:

None.

typedef void*(* tfNetBufCallback)(int anLen, void *apUser)

This prototype defines a callback function that is activated each time a new empty receive buffer is required.

Note:

The buffer must be at least the requested size, and must be L1 cache aligned.

Parameters:

[in]	anLen	The number of bytes required in the buffer.
[in]	apUser	A callback-specific parameter supplied when the callback is registered.

Returns:

Pointer to the buffer, or NULL if none could be allocated.
