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>

2019-09-05mt76: round up length on mt76_wr_copyFelix Fietkau
When beacon length is not a multiple of 4, the beacon could be sent with the last 1-3 bytes corrupted. The skb data is guaranteed to have enough room for reading beyond the end, because it is always followed by skb_shared_info, so rounding up is safe. All other callers of mt76_wr_copy have multiple-of-4 length already. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-09-05Bluetooth: mgmt: Use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct mgmt_rp_get_connections { ... struct mgmt_addr_info addr[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rp) + (i * sizeof(struct mgmt_addr_info)); with: struct_size(rp, addr, i) Also, notice that, in this case, variable rp_len is not necessary, hence it is removed.

2019-09-05bluetooth: hci_bcm: Give more time to come out of resetOndrej Jirman
Some supported devices need more time to come out of reset (eg. BCM4345C5 in AP6256). I don't have/found a datasheet, so the value was arrive at experimentally with the Oprange Pi 3 board.
