2019-06-27mt76: mt7603: improve hardware rate switching configurationFelix Fietkau1-1/+10
Now that tx status reporting can figure out the first attempted rate, we can make switching from lower rates to higher rates more conservative. This reduces retries under bad link conditions and ensures that fallback rates get more test coverage Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-06-27mt76: mt7603: rework and fix tx status reportingFelix Fietkau1-3/+2
Tx status reporting on mt7603 has a number of issues: - the hardware can alter the first rate index, but it is not reported to the driver - probing is very imprecise, because it alters the per-client rate set, but only considers info->status.rates for rate selection of a single probe packet - short/long GI selection has limitations, which are not accurately reported to mac80211 - if rates are changed while packets are in flight, tx status reports for the old rate set might be processed based on the new selection This led to very suboptimal rate selection with minstrel_ht. This patch completely reworks tx status reporting to get rid of these limitations: - Store the previous and current rate set in the driver + the TSF value at the time of the switch. - Use the tx status TSF value to determine which rate set needs to be used as reference. - Report only short or long GI rates for a single status event, not a mix. - The hardware reports the last used rate index. Use it along with the retry count to figure out what rate was used for the first attempt. - Use the same retry count value for all rate slots to make this calculation work. - Derive the probe rate from the current rateset instead of the skb cb - Do not wait for a status report for the probe frame before removing the probe rate from the rate table. Do it immediately after it was referenced in a tx status report. - Use the first half of the first rate retry budget for the probe rate in order to avoid using too many retries on that rate With this patch, throughput under bad link conditions is improved significantly, and there is a lot less rate fluctuation going on.

2019-05-01mt76: mt7603: fix initialization of max rx lengthFelix Fietkau1-1/+2
The previous version only accidentally disabled A-MSDU deaggregation by using the wrong mask for rx length configuration, which left previous length value in place.

2019-05-01mt76: fix tx power issuesFelix Fietkau1-0/+1
- tx power is stored in the channels after ieee80211_register_hw, so chan->orig_mpwr needs to be updated as well - for non-TSSI devices, mt76x2e needs to use a different target power value from the EEPROM - fix a rounding error in a few places (need to round up, not down) Signed-off-by: Felix Fietkau <nbd@nbd.name>
