ath11k: add debugfs for TWT debug calls
New debugfs files to manually add/delete/pause/resume TWT
dialogs for test/debug purposes.
The debugfs files expect the following parameters
- Add dialog
echo '<Peer_MAC> <Dialog_ID> <Wake_Interval_Usec> <Wake_Interval_Mantis>
<Wake_Duration_Usec> <First_SP_Offset> <TWT_Command>
<1:Broadcast /0:Individual> <1:Triggered / 0:Untriggered>
<1:Unannounced /0:Announced> <1:Protected / 0:Unprotected>' >
/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/add_dialog
Example (Non-triggered and un-announced):
echo '00:03:7F:20:13:52 1 102400 100 30720 20480 4 0 0 1 0' >
/sys/kernel/debug/ieee80211/phy0/netdev:wlan0/twt/add_dialog
- Delete dialog
echo '<Peer_MAC> <Dialog_ID>' >
/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/del_dialog
- Pause dialog
echo '<Peer_MAC> <Dialog_ID>' >
/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/pause_dialog
- Resume dialog
echo '<Peer_MAC> <Dialog_ID> <SP_Offset_Usec> <Next_TWT_Size>' >
/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/resume_dialog
Example:
echo '00:03:7F:20:13:52 1 2000000 3' >
/sys/kernel/debug/ieee80211/phy0/netdev:wlan0/twt/resume_dialog
