Subject: [PATCH] iwlwifi: audit single frames from AGG queue in RS
|
||||
|
||||
The rate scaling won't treat the information in a frame
|
||||
with IEEE80211_TX_CTL_AMPDU set if IEEE80211_TX_STAT_AMPDU
|
||||
is cleared. But all the frames coming from an AGG tx queue
|
||||
have IEEE80211_TX_CTL_AMPDU set, and IEEE80211_TX_STAT_AMPDU
|
||||
is set only if the frame was sent in an AMPDU.
|
||||
This means that all the data in frames in AGG tx queues that
|
||||
aren't sent as an AMPDU is thrown away.
|
||||
This is even more harmful when in bad link conditions, the
|
||||
frames are sent in an AMPDU and then finally sent as single
|
||||
frame. So a lot of failures weren't reported and the rate
|
||||
scaling got stuck in high rates leading to very poor
|
||||
connectivity.
|
||||
|
||||
Fix that by clearing IEEE80211_TX_CTL_AMPDU when the frame
|
||||
isn't part of an AMPDU.
|
||||
|
||||
This bug was introduced by
|
||||
|
||||
2eb81a40aa521035ff9c8c8309e482dff523f8c9
|
||||
iwlwifi: don't clear CTL_AMPDU on frame status
|
||||
|
||||
This fix basically reverts the aforementioned commit.
