Subject: [PATCH 43/49] Add support to configure TWT of a session using offset
|
|
in microseconds
|
|
|
|
Introduce a new cmd line argument "twt_offset=<u64>" in the existing list
|
|
of arguments supported in "$ wpa_cli twt_setup <args>" cmd to set the TWT
|
|
in terms of offset from the current remote TSF.
|
|
|
|
Example: To set a Target Wake Time of 102.4ms from the current remote TSF
|
|
|
|
$ wpa_cli twt_setup setup_cmd=0 min_twt=80 mantissa=38400 exponent=3 \
|
|
twt_offset=102400 trigger=0 implicit=1 flow_type=0 flow_id=5 \
|
|
control=0
