* mt76: add stbc entries to mt76_rate_powerFelix Fietkau2018-10-011-1/+2
| | | | | | | | | | | | | Add stbc tx power eeprom parsing support for mt76x2 driver. When writing power entries, make a distinction between rates that are read from the same EEPROM value, but have separate register entries. No effect on runtime behavior, but preparation for unification with mt76x0 and for placing restrictions on individual rate power limits Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

* mt76: use a per rx queue page fragment cacheFelix Fietkau2018-09-191-0/+1
| | | | | | | | | | | | | | | | Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragments. This can happen if the driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak.

| | | | | | | | | | Add tx_queue_skb function pointer in mt76_bus_ops since mt76x2u based devices do not map mt76x2_txwi on dma buffers and it is not possible to reuse mt76_dma_tx_queue_skb() routine to enqueue tx frames to hw buffers Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | | | | | | | | | | With software A-MPDU reordering in place, frames that notify mac80211 of powersave changes are reordered as well, which can cause connection stalls.

* mt76: validate rx CCMP PNFelix Fietkau2018-01-261-2/+10
| | | | | | | | | | | | | | Apparently hardware does not perform CCMP PN validation in hardware, so we need to take care of this in the driver. This is important for protecting against replay attacks. Since validation of fragmented frames is more complex, the CCMP header for those is preserved. To keep the counter in sync, the first fragment is verified by both mt76 and mac80211, and all other fragments only by mac80211.

* mt76: fix transmission of encrypted management framesFelix Fietkau2018-01-241-0/+1
| | | | | | | | | | | | Hardware encryption seems to break encrypted unicast mgmt tx. Unfortunately the hardware TXWI header does not have a bit to indicate that a frame is software encrypted, so sw-encrypted frames need to use a different WCID. For that to work, the CCMP PN needs to be generated in software, which makes things a bit slower, so only do it for keys that also need to tx management frames.
