2014-03-04rtlwifi: rtl8723ae: rtl8723-common: Create new driver for common codeLarry Finger10-469/+555
The drivers for RTL8723AE and RTL8723BE have some code in common. This commit creates a driver for this code that will be shared, and copies those common routines from rtl8723ae's phy code.

2014-03-04rtl818x: make sure TX descriptor writes are done before kicking DMAandrea merello1-0/+6
The TX descriptors are consumed by the HW using DMA. Even if in the driver code the TX descriptor writes appears before the HW "dma kick" register writes, the CPU may reorder them. If this happens, the TX may not happen at all becase the "valid" descriptor flag may have not been set yet. This patch adds a write memory barrier to ensures the TX descriptor is written before writing to the HW "dma kick" register.

2014-03-04rtl818x: Make sure the TX descriptor "valid" flag is written by lastandrea merello1-0/+5
The TX descriptors are consumed by the HW using DMA. Even if in the driver code the memory write that sets the "valid" flag appears after all other writes, the CPU may reorder writes, causing the HW to consider as valid a not-fully-written yet descriptor. This may cause HW incorrect behaviour. This can happen because (AFAIK) the HW may attempt DMA asynchronously without waiting to be kicked by the following register write. This patch adds a write memory barrier to enforce writes ordering.

2014-03-04ath9k_hw: tweak noise immunity thresholds for older chipsetsFelix Fietkau2-4/+23
Older chipsets are more sensitive to high PHY error counts, and the current noise immunity thresholds were based on tests run at QCA with newer chipsets. This patch brings back the values from the old ANI implementation for old chipsets, and it also disables weak signal detection on an earlier noise immunity level, to improve overall radio stability on affected devices.

2014-03-04ath9k_hw: toggle weak signal detection in AP mode on older chipsetsFelix Fietkau1-8/+10
The commit 80b4205b "ath9k: Fix OFDM weak signal detection for AP mode" prevented weak signal detection changes from taking effect in AP mode on all chipsets, claiming it is "not allowed". The main reason for not disabling weak signal detection in AP mode is that typically beacon RSSI is used to track whether it is needed to boost range, and this is unavailable in AP mode for obvious reasons. The problem with not disabling weak signal detection is that older chipsets are very sensitive to high PHY error counts. When faced with heavy noise, this can lead to an excessive amount of "Failed to stop TX DMA" errors in the field. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2014-02-28mwifiex: Track BA sequence number resetPaul Stewart3-7/+24
Some stations reset the sequence number for traffic-ids (TIDs) as they initiate a block-ACK session. In order to detect such behavior, mwifiex must note the starting sequence number given during the ADDBA request. If the first received sequence number after the ADDBA falls outside the receive window for this TID but after the the ADDBA starting sequence number, we can assume that this AP has reset its sequence number during the ADDBA. In this case we must adjust the input window backward to incorporate this received sequence number instead of ignoring it. Otherwise, we could fail to successfully retrieve an arbitrarily large number of downstream frames at the beginning of the block-ACK session.
