00005 *  Module Name:       Realtek 8019AS Driver Interface for uIP-AVR Port
00006 *
00007 *  Created By:        Louis Beaudoin (www.embedded-creations.com)
00008 *
00009 *  Original Release:  September 21, 2002
00010 *
00011 *  Module Description:
00012 *  Provides three functions to interface with the Realtek 8019AS driver
00013 *  These functions can be called directly from the main uIP control loop
00014 *  to send packets from uip_buf and uip_appbuf, and store incoming packets to
00015 *  uip_buf
00016 *
00017 *  September 30, 2002 - Louis Beaudoin
00018 *    Modifications required to handle the packet receive function changes in
00019 *      rtl8019.c.  There is no longer a need to poll for an empty buffer or
00020 *      an overflow.
00021 *    Added support for the Imagecraft Compiler
00022 *
