2017-08-03qtnfmac: implement cfg80211 channel_switch handlerSergey Matyukevich
This patch implements cfg80211 channel_switch handler enabling CSA channel-switch procedure. Driver performs only basic validation of the requested new channel and then sends command to firmware. Beacon IEs are not sent since beacon update is handled by firmware.

2017-08-03qtnfmac: move current channel info from vif to macSergey Matyukevich
Wireless cfg80211 core supplies channel settings in cfg80211_ap_settings structure for each BSS in multiple BSS configuration. On the other hand all the virtual interfaces on one radio are using the same PHY settings including channel. Move chandef structure from vif to mac structure in order to mantain the only instance of cfg80211_chan_def structure in qtnf_wmac rather than its multiple copies in qtnf_vif.

On startup driver obtains regulatory rules from firmware and enables them during wiphy registration. Later on regulatory domain change can be requested by host.

2017-08-03rtlwifi: Fix fallback firmware loadingSven Joachim
Commit f70e4df2b384 ("rtlwifi: Add code to read new versions of firmware") added code to load an old firmware file if the new one is not available. Unfortunately that code is never reached because request_firmware_nowait() does not wait for the firmware to show up and returns 0 even if the file is not there. Use the existing fallback mechanism introduced by commit 62009b7f1279 ("rtlwifi: rtl8192cu: Add new firmware") instead.

2017-08-01iwlwifi: implement fseq version mismatch warningMordechai Goodstein
During init, the FW checks whether the FSEQ value matches what it expects. If it doesn't match, we print a warning to let integrators clearly know that something is wrong. This can happen if another core (i.e. not WiFi) has updated the FSEQ version. This notification is only sent by the FW in production, for development firmwares, an assertion is triggered instead.

2017-08-01iwlwifi: mvm: refactor beacon template command codeLuca Coelho
We currently support 3 different versions of the beacon template command and the code does some tricks in order to reuse what is possible across these versions. But it is a bit complicated to read and soon there will be one more variation that the driver needs implement, which would complicate it even further. Refactor the way we send beacon template commands, which increases the code size a bit, but makes it much easier to read. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

There are two workarounds because RSS is currently broken on A000 devices due to firmware issues, but checking for the new TX API doesn't really make sense.

2017-08-01iwlwifi: reorganize firmware APIJohannes Berg

Reflect this in the source better and reorganize the firmware API to a new fw/api/ directory.

2017-08-01iwlwifi: mvm: set the RTS_MIMO_PROT bit in flag mask when sending sta to fwNaftali Goldstein
Set the STA_FLG_RTS_MIMO_PROT bit in station_flags_msk of the add sta command, so that when smps mode changes, the FW will know about it. In particular, in AP mode, clients are added upon receival of an auth request, at which point there's no knowledge of the client's smps mode. When the assoc request arrives, the add_sta command is resent to modify the station parameters. At this point the driver knows the smps mode, but since the corresponding bit in the mask is not set, the fw doesn't update this field so there's no rts protection for mimo.

2017-08-01iwlwifi: mvm: rs: fix TLC statistics collectionGregory Greenman
Statistics should be collected according to the actual rate a frame/aggregation was transmitted and not according to the initial rate from the last LQ command (these rates are different if the frames were retransmitted at a lower rate from the rate scale table).

2017-08-01iwlwifi: mvm: set A-MPDU bit upon empty BA notification from FWGregory Greenman
The bit was set only if there was at least one reclaimed frame in an aggregation. It's important to set it also in the case that the whole A-MPDU was lost, otherwise rate scaling statistics will not be updated correctly. Thus, set it always in ba notification handler. This fixes a throughput degradation of about 20% in certain scenarios with multiple streams on 11ac.

2017-08-01iwlwifi: split the regulatory rules when the bandwidth flags require itEmmanuel Grumbach
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.

2017-08-01iwlwifi: mvm: fix TCP CSUM offload with WEP and A000 seriesEmmanuel Grumbach
When we enabled TCP checksum offload, we need to tell the firmware where the IP header starts. If we have an IV, then we need to adapt that value since the IV is placed before the SNAP header. This is true only for cases where the driver adds the IV, not the WEP case in which the IV is added by the firmware itself. On A000 devices series, the IV is always added by the device. Fix this.
