Hi,
I am Saravana and i am currently working on adding statistics. It will
be really helpful if someone could provide me clarification related to
Last Tx Rate statistics.
In ieee80211_tx_status(), the Last Tx Rate (sta->last_tx_rate) update
happens only when the rate control is done by the HW
(IEEE80211_HW_HAS_RATE_CONTROL) .
My understanding is that irrespective of whether the rate control is
done by the hardware or not, the driver will fill up all the rates that
it had tried along with the retry count for each rate to
ieee80211_tx_status() using the
struct ieee80211_tx_info (info->status.rates).
The 'info->status.rates[rates_idx]' would point to the rate with which
the packet transmission has occured irrespective of the where the rate
control is done.
Could somebody clarify why the statistics update happens only when the
rate control is done by the hardware(flag IEEE80211_HW_HAS_RATE_CONTROL
is set)?
Thanks,
Saravana
