[Madwifi-devel] (Ab)Using the WLAN stack

[Ace E. <ace...@gm...>]

I'm trying to play around with creating some raw 802.11 frames using
my atheros card. I created an ioctl in ath_ioctl() which right now I'm
using to call ieee80211_send_disassoc(). The call seems to succeed (no
error messages or anything, and when I set ath_debug, I do see the
frame being printed to dmesg), but for some reason no packets are
appearing on the wire. I see no checks to refuse to send certain
packet types in any of the open source code.

Is there anything going on in the closed source HAL I need to be aware
of? Does it refuse to send packets depending card state, mac address,
bssid or something? If I try to lie to the card and set
sc->sc_ic.ic_state = IEEE80211_S_RUN, I still see nothing. Using
iwconfig to set the modes to ad-hoc, managed, or master seems to also
make no difference.

Anyone have any advice?
