Due to the limitation of wmi tlv parsing logic, if there are two parameters in a wmi event with same tlv tag, we can get only the last value, as it overwrites the prev value of the same tlv tag.

2017-12-14wcn36xx: Add hardware scan offload supportLoic Poulain4-8/+238
Current hw_scan implementation does not trigger offloaded hardware scan and seems to only put the device in a kind of listening mode (beacon/probe-response) for software scan. Since no probe request are generated by the software, current scanning method is similar to a passive scan. This patch introduces support for 'true' hardware offloaded scan. Hardware scan is configured and started via the start-scan-offload firmware message. Once scan has been completed a scan indicator message is received from firmware. Moreover, this patch includes support for directed probe-request, allowing connection with hidden APs. It also fixes scan issues with band-steering AP which are not 'visible' with passive scan (due to hidden ssid in beacons). Let's keep the 'legacy' scanning method in case scan-offload is not supported. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2017-12-14ath10k: search DT for qcom,ath10k-calibration-variantSven Eckelmann1-7/+33
Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified on QCA4019 using bus, bmi-chip-id and bmi-board-id. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8. Something similar has to be provided for systems without SMBIOS but with device trees. No solution was specified by QCA and therefore a new one has to be found for ath10k. The device tree requires addition strings to define the variant name wifi@a000000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; wifi@a800000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; This would create the boarddata identifiers for the board-2.bin search * bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U * bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U Signed-off-by: Sven Eckelmann <sven.eckelmann@openmesh.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2017-12-14ath10k: add per peer tx stats support for 10.2.4Anilkumar Kolli4-1/+104
10.2.4 firmware branch (used in QCA988X) does not support HTT_10_4_T2H_MSG_TYPE_PEER_STATS and that's why ath10k does not provide tranmission rate statistics to user space, instead it just shows hardcoded 6 Mbit/s. But pktlog firmware facility provides per peer tx statistics. The firmware sends one pktlog event for every four PPDUs per peer, which include: * successful number of packets and bytes transmitted * number of packets and bytes dropped * retried number of packets and bytes * rate info per ppdu Firmware supports WMI_SERVICE_PEER_STATS, pktlog is enabled through ATH10K_FLAG_PEER_STATS, which is nowadays enabled by default in ath10k. This patch does not impact throughput. Tested on QCA9880 with firmware version 10.2.4.70.48. This should also work with firmware branch 10.2.4-1.0-00029 Parse peer stats from pktlog packets and update the tx rate information per STA. This way user space can query about transmit rate with iw: $iw wlan0 station dump Station 3c:a9:f4:72:bb:a4 (on wlan1) inactive time: 8210 ms rx bytes: 9166 rx packets: 44 tx bytes: 1105 tx packets: 9 tx retries: 0 tx failed: 1 rx drop misc: 3 signal: -75 [-75, -87, -88] dBm signal avg: -75 [-75, -85, -88] dBm tx bitrate: 39.0 MBit/s MCS 10 rx bitrate: 26.0 MBit/s MCS 3 rx duration: 23250 us authorized: yes authenticated: yes associated: yes preamble: short WMM/WME: yes MFP: no TDLS peer: no DTIM period: 2 beacon interval:100 short preamble: yes short slot time:yes connected time: 22 seconds Signed-off-by: Anilkumar Kolli <akolli@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2017-12-14ath10k: unify rx processing in napi_pollRajkumar Manoharan3-61/+63
With current NAPI implementation, NAPI poll can deliver more frames to net core than allotted budget. This may cause warning in napi_poll. Remaining quota is not accounted, while processing amsdus in rx_in_ord_ind and rx_ind queue. Adding num_msdus at last can not prevent delivering more frames to net core. With this change, all amdus from both in_ord_ind and rx_ind queues are processed and enqueued into common skb list instead of delivering into mac80211. Later msdus from common queue are dequeued and delivered depends on quota availability. This change also simplifies the rx processing in napi poll routine.

2017-12-14ath10k: handling qos at STA side based on AP WMM enable/disableBalaji Pothunoori1-1/+1
Data packets are not sent by STA in case of STA joined to non QOS AP (WMM disabled AP). This is happening because of STA is sending data packets to firmware from host with qos enabled along with non qos queue value(TID = 16). Due to qos enabled, firmware is discarding the packet. This patch fixes this issue by updating the qos based on station WME capability field if WMM is disabled in AP. This patch is required by 10.4 family chipsets like QCA4019/QCA9888/QCA9884/QCA99X0. Firmware Versoin : 10.4-3.5.1-00018. For 10.2.4 family chipsets QCA988X/QCA9887 and QCA6174 this patch has no effect.

2017-12-07ath10k: move spectral scan support under a separate config symbolMatthias Schiffer3-4/+11
At the moment, spectral scan support, and with it RELAY, is always enabled with ATH10K_DEBUGFS. Spectral scan support is currently the only user of RELAY in ath10k, and it unconditionally reserves a relay channel. Having debugfs support in ath10k is often useful even on very small embedded routers, where we'd rather like to avoid the code size and RAM usage of the relay support. While ath10k-based devices usually have more resources than ath9k-based ones, it makes sense to keep the configuration symmetric to ath9k, so the same base kernel without RELAY can be used for both ath9k and ath10k hardware.

Since then, we have not seen the TXQ-related regression, so it should be safe to re-enable TXQs.

2017-11-27mac80211: use QoS NDP for AP probingJohannes Berg1-1/+1
When connected to a QoS/WMM AP, mac80211 should use a QoS NDP for probing it, instead of a regular non-QoS one, fix this. Change all the drivers to *not* allow QoS NDP for now, even though it looks like most of them should be OK with that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2017-11-20wcn36xx: fix iris child-node lookupJohan Hovold1-1/+1
Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent mmio node was also prematurely freed.

2017-11-20ath10k: fix data rx for CCMP-256, GCMP and GCMP-256 in raw modeVasanthakumar Thiagarajan1-13/+38
Make sure 16-byte mic is removed from the rx data packet tail when CCMP-256, GCMP and GCMP-256 ciphers are used in raw decap mode. This fixed rx traffic failures in those ciphers in raw mode. Split the helper returning crypto tail length into two, one to get the ICV length and other to get the mic lengh for the cipher to make it clean.

Pull networking updates from David Miller: "Highlights: 1) Maintain the TCP retransmit queue using an rbtree, with 1GB windows at 100Gb this really has become necessary. From Eric Dumazet. 2) Multi-program support for cgroup+bpf, from Alexei Starovoitov. 3) Perform broadcast flooding in hardware in mv88e6xxx, from Andrew Lunn. 4) Add meter action support to openvswitch, from Andy Zhou. 5) Add a data meta pointer for BPF accessible packets, from Daniel Borkmann. 6) Namespace-ify almost all TCP sysctl knobs, from Eric Dumazet. 7) Turn on Broadcom Tags in b53 driver, from Florian Fainelli. 8) More work to move the RTNL mutex down, from Florian Westphal. 9) Add 'bpftool' utility, to help with bpf program introspection. From Jakub Kicinski. 10) Add new 'cpumap' type for XDP_REDIRECT action, from Jesper Dangaard Brouer. 11) Support 'blocks' of transformations in the packet scheduler which can span multiple network devices, from Jiri Pirko. 12) TC flower offload support in cxgb4, from Kumar Sanghvi. 13) Priority based stream scheduler for SCTP, from Marcelo Ricardo Leitner. 14) Thunderbolt networking driver, from Amir Levy and Mika Westerberg. 15) Add RED qdisc offloadability, and use it in mlxsw driver. From Nogah Frankel. 16) eBPF based device controller for cgroup v2, from Roman Gushchin. 17) Add some fundamental tracepoints for TCP, from Song Liu. 18) Remove garbage collection from ipv6 route layer, this is a significant accomplishment.
