2019-09-05mt76: mt7615: fix using VHT STBC ratesFelix Fietkau
The hardware expects MT_TX_RATE_NSS to be filled with the number of space/time streams. For non-STBC rates, this is equal to nss. For 1-stream STBC, this needs to be set to 2. This is relevant for VHT rates only, on HT, the value is derived from MCS internally. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-09-05mt76: mt7615: sync with mt7603 rate control changesFelix Fietkau
- 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 - Switch from lower rates to higher rates more conservatively - enable hardware rate up/down selection Reviewed-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
