/*****************************************************************************
*  Module Name:       Realtek 8019AS Driver Interface for uIP-AVR Port
*
*  Created By:        Louis Beaudoin (www.embedded-creations.com)
*
*  Original Release:  September 21, 2002
*
*  Module Description:
*  Provides three functions to interface with the Realtek 8019AS driver
*  These functions can be called directly from the main uIP control loop
*  to send packets from uip_buf and uip_appbuf, and store incoming packets to
*  uip_buf
*
*  September 30, 2002 - Louis Beaudoin
*    Modifications required to handle the packet receive function changes in
*      rtl8019.c.  There is no longer a need to poll for an empty buffer or
*      an overflow.
*    Added support for the Imagecraft Compiler
*

*                 will fit in uip_buf, it is retreived, and the length is
*                 returned.  A packet bigger than the buffer is discarded
