2019-09-05mt76: mt76x0: remove unneeded return value on set channelStanislaw Gruszka3-16/+9
We allways return 0 from mt76x0_phy_set_channel(), no need to pass return value upward. Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>

2019-09-05mt76: remove offchannel check in tx schedulingFelix Fietkau3-10/+2
tx queues are already disabled by mac80211 during scanning or other off-channel activity. There is no need to repeat the check in mt76, since scheduled queues are selected by mac80211 as well. Signed-off-by: Balakrishna Bandi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-09-05mt76: do not send BAR frame on tx aggregation flush stopFelix Fietkau3-3/+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 <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>

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 <[email protected]>

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 <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
