2019-10-04mac80211: simplify TX aggregation startJohannes Berg1-2/+1
There really is no need to make drivers call the ieee80211_start_tx_ba_cb_irqsafe() function and then schedule the worker if all we want is to set a bit. Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.

2019-09-05mt76: do not send BAR frame on tx aggregation flush stopFelix Fietkau1-1/+0

2019-09-05mt76: mt7615: apply calibration-free data from OTPFelix Fietkau1-0/+38
MT7615 chips usually come pre-calibrated, even when used on embedded boards. In that case, the on-flash EEPROM data needs to be merged with some data from OTP ROM. Run this merge if the external EEPROM data is valid and OTP has valid fields. Tested-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-09-05mt76: mt7615: fix PS buffering of action framesFelix Fietkau1-1/+1
Bufferable management frames need to be put in the data queue, otherwise they will not be buffered when the receiver is asleep. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-09-05mt76: mt7615: fix using VHT STBC ratesFelix Fietkau1-6/+12
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 Fietkau4-44/+124
- 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>
