Not able to set u-apsd for P2P client

Not able to set u-apsd for P2P client

[Krishna Chaitanya]

Hi,

We are having trouble making the uapsd working in p2p client case. Is
this broken? or is there a way to configure the uapsd for p2p client
case?


case a) p2p client with p2p_no_group_iface=1

When trying to change the mode from MANAGED to P2P_CLIENT the sdata is
being cleared so the previous change of uapsd_queue=0xF is being
cleared and default value is taken.

case b) with p2p_no_group_iface=0

As the interface is dynamically created, we cannot use the mac80211
debugfs to set the uapsd_queues.
I have tried "wpa_cli p2p_set client_apsd 1,1,1,1" but it is not taking effect.

Thanks,
Regards,
Chaitanya T K.

May be this is more of a mac80211 issue, currently while preparing
association request frame mac80211 uses imgd->uapsd_queues, so
need fetch that information from usespace up on interface addition viz.
a nl command? curently only NL command which has this info is ADD_STA
which is used in TDLS case.

Any ideas are appreciated.
