Proxim 8470 using madwifi checked out 8/14/05: ath_pci=0.9.6, ath_hal=
0.9.14.9 <http://0.9.14.9>

I've just recently learned the new madwifi is out but haven't had a chance
to compile it. I'll investigate broadcast issues but it also seems to be
some interaction with wpa_supplicant since without wpa_supplicant, B can get
to A without A pinging B.
