SMPS for AP mode confoguration

[Krishna Chaitanya]

Hi,

We are testing SMPS functionality for AP mode. The driver conveys its
capabilities through setting the HT capability which can be set to 0-3.

I wanted to convey support for both Dynamic and Static Powersave
and then control the config through hostapd.conf file. Currently this is
not possible.From driver i can only advertize support for static (or) dynamic
not both (HW_SUPPORTS_* is a different thing which is used in
doing checks at debugfs level).

So if i wanted to configure different modes from hostapd.conf, i
have to change the driver settings as well.

Shouldn't it be the other way around, based on driver's _HW_ flags
we should convey the capabilities to user-space (currently we use
ht_cap for this) and it will configure the mode from the configuration
file. I think the design of SMPS configuration should be changed.

this was recently changed. take a look at this patchset:
http://www.spinics.net/lists/linux-wireless/msg126749.html

we also have a matching supplicant patchset that will probably be
upstreamed soon.

Thanks Ellad, it looks good to me, will try out them once they are up stream.
