2020-03-06wil6210: reject unsupported coalescing paramsJakub Kicinski

Lots of mt76 patches as they missed the v5.6 deadline and hence they were postponed to the next version. Otherwise nothing special standing out. mt76 Major changes: * dual-band concurrent support for MT7615 * fixes for rx path race conditions * coverage class support for MT7615 * beacon fixes for USB devices * MT7615 LED support * set_antenna support for MT7615 * tracing improvements * preparation for supporting new USB devices * tx power fixes brcmfmac * support BRCM 4364 found in MacBook Pro 15,2 ==================== Signed-off-by: David S.

2020-03-03mt76: fix array overflow on receiving too many fragments for a packetFelix Fietkau
If the hardware receives an oversized packet with too many rx fragments, skb_shinfo(skb)->frags can overflow and corrupt memory of adjacent pages. This becomes especially visible if it corrupts the freelist pointer of a slab page.

2020-02-24mac80211_hwsim: enable Beacon protectionJouni Malinen
Now that there is support for BIGTK configuration and AP/STA functionality for using BIP with Beacon frames, indicate support for the Beacon protection functionality. Johannes: move this to hwsim, since it's not clear that all drivers using mac80211 will do this correctly - lots of them modify the beacon before transmission e.g. to update the TIM element, and that would obviously break the signature.

2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device().

2020-02-14mt76: mt7615: rely on mt76_queues_read for mt7622Lorenzo Bianconi
As previous devices, mt7622 relies on multiple hw queues while for mt7615 we have just on per band hw queue and the mcu demux the traffic according to the packet AC. In order to dump all configured hw queues, rely on mt76_queues_read for mt7622 in mt7615 debugfs Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: do not set HOST_BROADCAST_PS_BUFFERING for mt7615Felix Fietkau
mt7615 handles powersave buffering in firmware Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: rework rx phy index handlingFelix Fietkau
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware could potentially write it again. Since there is no PHY index indication in the rx info, we need to use another way: If both PHYs are using different channels, find the PHY where chfreq matches the register value. The only corner case remaining is when both PHYs are using the same channel. In that case, the per-packet noise value on the primary PHY will have information belonging to the chains of the secondary PHY from the previous received packet of that PHY. The secondary PHY will set noise to 0 for extra chains. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: fix rounding issues on converting per-chain and combined txpowerFelix Fietkau
Unify code converting between the different txpower values. Always add/remove the combined txpower delta before dividing half-dB values. Also fix the combined txpower delta values. The correct half-dB delta for 3 chains is 9, not 8. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt76x2: avoid starting the MAC too earlyFelix Fietkau
Do not set the tx/rx start bits in MT_MAC_SYS_CTRL from within initvals. The driver sets these later when the hardware is ready Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-02-14mt76: mt7615: fix and rework tx power handlingFelix Fietkau
Setting the tx power by manipulating EEPROM may in some cases not be enough, since it only covers the base target power and not per-rate offsets. In other cases, it could limit tx power of rates too much, possibly reducing throughput or range. Use firmware support for applying per-rate limit and power offsets for different values of Nss.
