Subject: cfg80211_ops

Hi,

Is some one able to please confirm for me that the following
cfg80211_ops callbacks are enough to implement a minimal functioning
Wi-Fi driver. Assume that a virtual interface is added during driver
initialization.

scan
add_key
get_key
del_key
sat_default_key
connect
disconnect
set_wiphy_params

thanks,
Tobin

correct (if brcmfmac is).

Thanks for the response Igor. Yes, infrastructure mode only.

Cool, thank you.

For really basic operation, I don't think you need that, and might even
be able to get away withou set_wiphy_params.

Also, set_default_key is, IIRC, not needed in WPA/WPA2 client mode, but
may be needed for WEP - not sure off the top of my head.

Hi, is this for STA-only? I guess you also need
mgmt_frame_register
mgmt_tx

and you don't need *_key callbacks in case its fine to operate without
encryption.
