Now tcpip_output() is a function pointer that is supposed to be set via the macro tcpip_set_outputfunc(). Packet drivers do so on process startup. Thus if there are several packet drivers in a Contiki system the one started last is the one actually used. This behaviour is especially useful for the 'IP forwarding' "meta" packet driver.

/*****************************************************************************
|
|
* 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
|
|
*
