hostap setup problem

You need to re-compile with the EXTRA_CFLAG option
in the README.prism2 file.

Host AP configuration for IEEE 802.1X

Host AP driver includes and Authenticator implementation in the user
space daemon. When using this Authenticator, the driver needs to be
compiled for user space management functionality, i.e., with
PRISM2_HOSTAPD defined. This is not the default option, so an
additional configuration is needed. This can be added by editing
driver/modules/hostap_config.h, or more easily by using EXTRA_CFLAGS


After this, the kernel driver should be installed and the kernel
modules loaded to initialize the wireless LAN card. In addition, the
user space daemon needs to be build:

cd hostapd

Hope this helps
