Rejecting non-native endian BTF overlapped with the addition of support for it. The rest were more simple overlapping changes, except the renesas ravb binding update, which had to follow a file move as well as a YAML conversion. Signed-off-by: David S. Miller <davem@davemloft.net>

2020-09-24mt76: mt7663s: introduce sdio tx aggregationLorenzo Bianconi2-15/+46
Introduce sdio tx aggregation to reduce bus transaction ands improve tx throughput. For the moment the skb are copied in a dedicated buffer since mmc APIs do not support sg table for zero-copy. Since skb data are already copied in xmit_buff[], avoid linearization in ma80211 layer. Relying on tx aggregation, we improve tx tpt of ~65%.

2020-09-24mt76: rely on AQL for burst size limits on tx queueingFelix Fietkau3-3/+10
Now that AQL works well on all mt76 drivers, completely replace the arbitrary burst sizing and number of bursts logic for tx scheduling. For the short period of time in which AQL does not work well yet, limit each stations to 16 in-flight packets that have no estimated tx time. This should avoid filling the queue if a station connects and queues up a large number of packets before rate control information is available, especially with hardware rate control Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-09-24mt76: mt7615: significantly reduce interrupt loadFelix Fietkau4-25/+20
On 7615 and newer, DMA completion only triggers unmap, but not free of queued skbs, since pointers to packets are queued internally. Because of that, there is no need to process the main data queue immediately on DMA completion. To improve performance, mask out the DMA data queue completion interrupt and process the queue only when we receive a txfree event. This brings the number of interrupts under load down to a small fraction. Signed-off-by: Felix Fietkau <nbd@nbd.name>

Initialize set_drv_ctrl and set_fw_ctrl function pointers in mt7663s_mcu_init. This is a preliminary patch to enable runtime-pm for mt7663s chipset. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

MT_EE_WIFI_CONF field can be used to detect if the chipset is MT7615D. Thus, add support to automatically register ext_phy if DBDC is detected. Signed-off-by: Shayne Chen <shayne.chen@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7615: reduce maximum VHT MPDU length to 7991Felix Fietkau1-1/+1
After fixing mac80211 to allow larger A-MSDUs in some cases, there have been reports of performance regressions and packet loss with some clients. It appears that the issue occurs when the hardware is transmitting A-MSDUs bigger than 8k. Limit the local VHT MPDU size capability to 7991, matching the value used for MT7915 as well.

Two minor conflicts: 1) net/ipv4/route.c, adding a new local variable while moving another local variable and removing it's initial assignment. 2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes. One pretty prints the port mode differently, whilst another changes the driver to try and obtain the port mode from the port node rather than the switch node. Signed-off-by: David S.

2020-08-27mt76: mt7615: use v1 MCU API on MT7615 to fix issues with adding/removing ↵Felix Fietkau1-1/+2
stations The implementation of embedding WTBL update inside the STA_REC update is buggy on the MT7615 v2 firmware. This leads to connection issues after a station has connected and disconnected again. Switch to the v1 MCU API ops, since they have received much more testing and should be more stable. On MT7622 and later, the v2 API is more actively used, so we should keep using it as well.
