Based on the powersave comments I had earlier, maybe we should remove
that bit for now? Work items here require powersave is disabled, but we
won't do that right now if we're on the same channel.
Scan, on the other hand, will still disable powersave (right?)
With regard to scanning and power-save: If we are scanning on
channel, I think we should still be able to receive normal traffic.
The offchannel_ps_enable has this comment:
/*
* inform AP that we will go to sleep so that it will buffer the frames
* while we scan
*/
static void ieee80211_offchannel_ps_enable(struct ieee80211_sub_if_data *sdata)
So, do we really need to call this method for on-channel scanning?
My naive assumption is that we would actually want the NIC to disable it's
local power-save logic while we are scanning so that it doesn't
get sleepy and miss beacons?
Thanks,
Ben
