2016-04-06rtlwifi: btcoexist: Implement antenna selectionLarry Finger
The previous patch added an option to rtl8723be to manually select the antenna for those cases when only a single antenna is present, and the on-board EEPROM is incorrectly programmed. This patch implements the necessary changes in the Bluetooth coexistence driver.

2016-04-06rtlwifi: rtl8723be: Add antenna select module parameterLarry Finger
A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver.

2016-04-05mac80211: allow not sending MIC up from driver for HW cryptoSara Sharon
When HW crypto is used, there's no need for the CCMP/GCMP MIC to be available to mac80211, and the hardware might have removed it already after checking. The MIC is also useless to have when the frame is already decrypted, so allow indicating that it's not present. Since we are running out of bits in mac80211_rx_flags, make the flags field a u64.

2016-04-04ath10k: combine txrx and replenish taskRajkumar Manoharan
Since tx completion and rx indication processing are moved out of txrx tasklet and rx ring lock contention also removed from txrx for rx_ind messages, it would be efficient to combine both replenish and txrx tasks. Refill threshold is adjusted for both AP135 and AP148 (low and high end systems). With this adjustment in AP135, TCP DL is improved from 603 Mbps to 620 Mbps and UDP DL is improved from 758 Mbps to 803 Mbps. Also no watchdog are observed on UDP BiDi.

2016-04-04ath10k: reuse copy engine 5 (htt rx) descriptorsRajkumar Manoharan
Whenever htt rx indication i.e target to host messages are received on rx copy engine (CE5), the message will be freed after processing the response. Then CE 5 will be refilled with new descriptors at post rx processing. This memory alloc and free operations can be avoided by reusing the same descriptors. During CE pipe allocation, full ring is not initialized i.e n-1 entries are filled up. So for CE 5 full ring should be filled up to reuse descriptors. Moreover CE 5 write index will be updated in single shot instead of incremental access. This could avoid multiple pci_write and ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019 platform. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-04-04ath10k: cleanup copy engine receive next completionRajkumar Manoharan
The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. For diag register read and write operations, 'paddr' is stored in transfer context. ath10k doesn't rely on the meta/transfer_id. So the unused output arguments {bufferp, nbytesp and transfer_idp} are removed from CE recv_next completion.

Except qca61x4 family chips (qca6164, qca6174), copy engine 5 is used for receiving target to host htt messages. In follow up patch, CE5 descriptors will be reused. In such case, same API can not be used as htc layer callback where the response messages will be freed at the end. Hence register new API for HTC layer that free up received message and keep the message handler common for both HTC and HIF layers.

2016-04-04ath10k: speedup htt rx descriptor processing for rx_indRajkumar Manoharan
In follow up patch, htt rx descriptors will be reused instead of dealloc and refill. To achieve that htt rx indication messages should not be deferred and should be processed in pci tasklet itself. Also from rx indication message, mpdu_count alone is used. So it is maintained as atomic variable and all rx amsdu handlers are done processed from txrx tasklet. This change get rid of rx_compl_q usage. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-04-04ath10k: cleanup amsdu processing for rx indicationRajkumar Manoharan
Make amsdu handlers (i.e amsdu_pop and rx_h_handler) common to both rx_ind and frag_ind htt events. It is sufficient to hold rx_ring lock for amsdu_pop alone and no need to hold it until the packets are delivered to mac80211. This helps to reduce rx_lock contention as well.
