Interface doesn't accept private ioctl...

[Rubén González]

Hi all. Here is my problem:

I'm trying to set aditional information elements into beacon frames through
a simple program that manages SIOCSIWGENIE ioctl. I have based the code on
the one of the iwpriv program, so it didn't take me to long to write and
compile. The fact is that the calling to this ioctl always returns a
negative value, that is that this interface doesn't accept this private
ioctl. I'm using a 3Com card Intersil Prism 2.5 chipset based with updated
station firmware to 1.8.2, and a linux kernel version 2.6.18. Does anybody
have an idea about how to make this ioctl work at the AP wlan0 interface? Is
there a patch or similar needed? Is it recomended to update the kernel
version to 2.6.24 or higher and make use of the mac80211 stack?

Thanks in advance.
