如何再end驱动中支持wpa

希望使用vxworks原有的802。1x功能！

谢谢！指教！

VxWorks自己带有WindNet 802.1x 模块，802.11bDDK中也说到了 如何支持，主要通过IOCTL，
EIOCSAUTHCALLBACK
Register authentication callback
Registers a new function to replace the old callback routine. This routine is called each time a new station authenticates. No response is required. This routine is in addition to that used by EIOCASTA, although to make full use of this extension, that list should be empty. Data is a function pointer to the function, NULL to disable.


to replace the old callback routine
请问替代的是哪个routine?
谢谢了！
