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 Fietkau4-41/+108
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.

2019-06-27mt76: mt76x02: fix tx reordering on rate control probing without a-mpduFelix Fietkau2-2/+4
To avoid aggregating rate control probing packets with other traffic, and to ensure that the probing rate gets used, probing packets get assigned a different internal queueing priority. This causes packets to be transmitted in a different order, which is compensated by the receiver side reordering. However, if A-MPDU is disabled, this reordering can become visible to upper layers on the receiver side. Disable the priority change if A-MPDU is disabled. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-06-27mt76: mt76x02: fix tx status reporting issuesFelix Fietkau4-20/+109
When the hardware falls back to lower rates for a transmit attempt, only the first status report will show the number of retries correctly. The frames that follow will report the correct final rate, but number of retries set to 0. This can cause the rate control module to vastly underestimate the number of retransmissions per rate. To fix this, we need to keep track of the initial requested tx rate per packet and pass it to the status information. For frames with tx status requested, this is simple: use the rate configured in info->control.rates[0] as reference. For no-skb tx status information, we have to encode the requested tx rate in the packet id (and make it possible to distinguish it from real packet ids). To do that, reduce the packet id field size by one bit, and use that bit to indicate packet id vs rate. This change also improves reporting by filling the status rate array with rates from first rate to final rate, taking the same steps as the hardware fallback table. This matters in corner cases like MCS8 on HT, where the fallback target is MCS0, not MCS7. Signed-off-by: Felix Fietkau <nbd@nbd.name>
