* mac80211: pass block ack session timeout to to driverSara Sharon2017-01-06
| | | | | | | | | | | | Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

* ath10k: set SM power save disabled to default valuePeter Oh2017-01-06
| | | | | | | | | | | | | | | | | Use SMPS disabled as default because FW does not indicate any support of SMPS. This change will help STAs out that don’t support SMPS from sticking on 1SS, since they don’t have method to change it back to multiple chains. This change also should not affect power consumption of STAs supporting SMPS, because they are capable to switch the mode to dynamic or static either at the end of frame sequence or by using SMPS action frame.

* ath10k: wake up device before accessing registersRajkumar Manoharan2017-01-06
| | | | | | | | | | | | | | commit 1aaf8efba0ae ("ath10k: disable PCI PS for QCA988X and QCA99X0") partially reverts pci soc powersave support added by commit 77258d409ce4 ("ath10k: enable pci soc powersaving"). While reverting the change, pci wake up function is called after accessing pci registers instead of prior to access. The assumption is that chip is woken up before accessing its registers.Though this change does not fix any known issues, this might help to avoid unknown or low power platform specific issues.

* ath10k: allow Mesh Point to install peer security keyPeter Oh2017-01-06
| | | | | | | | | | | | | Mesh Point requires peer security key install when running in secured mode since it's a type of peer links, otherwise peer link will be removed due to key install failure. MFP feature set is required to run Mesh in secured mode and QCA988X firmware, 10.2.4.70.14-2 and above, is the only one supporting secured Mesh at this moment.

* ath10k: apply Mesh subtype when Mesh interface created.Peter Oh2017-01-06
| | | | | | | | | | | | | | | | | QCA988X firmware starting from 10.2.4.70.12-2 has capability to support Mesh Control Field Present bit in QoS field in native Wi-Fi mode. Hence apply Mesh subtype according to the WMI service map. Firmware will allows unicast, broadcast, multicast, and WDS frame (FromDS = 1 and ToDS = 1) to be received via the interface, once Mesh subtype is used. The firmware and this patch together make native Wi-Fi mode comply to IEEE802.11s Mesh frame in open mode, but the firmware doesn't yet support secured Mesh mode.

* ath10k: fix peerid configuration in htt tx desc for htt version < 3.4Vasanthakumar Thiagarajan2017-01-06
| | | | | | | | | | | | | | | | | | | Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses LSB 16-bit for frequency configuration which is used for offchannel tx and MSB 16-bit is for peerid. But other firmwares using version 2.X (10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx desc. So far no issue is found with the existing code setting peerid and freq for HTT version 2.X, this could be mainly because of 0 as frequecy (home channel) is being always passed with those firmwares. There may be issues when non-zero freq is passed with firmware using < 3.4 htt version. To be safe use target_version_major and target_version_minor along with htt-op-version before configuring peer id and freq in htt tx desc. This patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv and uses the helper while setting peerid in htt_tx_desc.

This WMI command mismatch between host and firmware does not cause any real issues because this new member is not used in 10.4 firmwares so far (10.4.1.00030-1).
