/*****************************************************************************
* 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
*

* Description: Polls the RTL8019 looking for an overflow condition or a new
* packet in the receive buffer. If a new packet exists and
* will fit in uip_buf, it is retreived, and the length is
* returned. A packet bigger than the buffer is discarded
