Hello,
I have two short questions about power saving in mac80211:
1) Is there support in the linux kernel for power saving when in AdHoc mode ?
According to the docs, announcement messages called ATIM
(announcement traffic indication messages) should be sent.
Yet, grepping under net/wireless/mac for atim does not find anything
(except one comment line in mlme.c).
2) As I find out from the docs, there should be no buffering for ordered frames.
When we handle multicast frames, there is a check for oredring;
In ieee80211_tx_h_multicast_ps_buf() there is a call to ieee80211_has_order()
and we do not buffer the packet when there is ordering.
On the other hand , when we handle unicast packets, there is no check
for ordering (see: ieee80211_tx_h_unicast_ps_buf()).
My question is: shouldn't we check ordering also for unicast packets?
Regards,
Mark
