2018-07-31wil6210: add 3-MSI supportAlexei Avshalom Lazar
Extend MSI support to 3-MSI in order to load balance the tx\rx interrupts between different cores. use_msi module parameter has changed to n_msi. Usage: - Set n_msi to 0 for using INTx - Set n_msi to 1 for using single MSI - Set n_msi to 3 for using 3-MSI In 3-MSI configuration MSI 0 is used for TX interrupts, MSI 1 is used for RX interrupts and MSI 2 is used for MISC interrupts.

2018-07-31wil6210: fix RX checksum report to network stackMaya Erez
Currently the driver sets CHECKSUM_UNNECESSARY only in case the HW doesn't report checksum error. As ip_summed value is not initialized it is not clear what the driver will report to the network stack in case of HW checksum error or in case HW doesn't calculate checksum. Initialize ip_summed to CHECKSUM_NONE to guarantee checksum calculation by the network stack in the above cases.

2018-07-31ath9k_hw: fix channel maximum power level testFelix Fietkau
The tx power applied by set_txpower is limited by the CTL (conformance test limit) entries in the EEPROM. These can change based on the user configured regulatory domain. Depending on the EEPROM data this can cause the tx power to become too limited, if the original regdomain CTLs impose lower limits than the CTLs of the user configured regdomain. To fix this issue, set the initial channel limits without any CTL restrictions and only apply the CTL at run time when setting the channel and the real tx power.

2018-07-31ath10k: prevent active scans on potential unusable channelsSven Eckelmann
The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the scan. This results in transmission (probe requests) on channels which are not "available" for transmissions. Since the firmware is closed source and nothing can be done from our side to fix the problem in it, the driver has to work around this problem. The WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not scan actively on a channel unless an AP was detected on it. Simple probe requests will then be transmitted by the STA on the channel. ath10k must therefore also use this flag when it queues a radar channel for scanning. This should reduce the chance of an active scan when the channel might be "unusable" for transmissions.

2018-07-31brcmfmac: specify some features per firmware versionRafał Miłecki
Some features supported by firmware aren't advertised and there is no way for a driver to query them. This includes e.g. monitor mode details. Most firmwares support monitor interface but only the latest ones /announce/ it with a "monitor" flag in the "cap" iovar. There isn't any reliable detection method for older firmwares (BRCMF_C_MONITOR was tried but "it only indicates the core part of the stack supports"). Similarly support for tagging monitor frames and building radiotap headers can't be reliably detected for all firmwares. This commit adds table that allows mapping features to firmware version. It adds mappings for 43602a1 and 4366b1 firmwares from linux-firmware.git. Both were confirmed to be passing monitor frames.

2018-07-30hv_netvsc: Add per-cpu ethtool stats for netvscYidong Ren
This patch implements following ethtool stats fields for netvsc: cpu<n>_tx/rx_packets/bytes cpu<n>_vf_tx/rx_packets/bytes Corresponding per-cpu counters already exist in current code. Exposing these counters will help troubleshooting performance issues. for_each_present_cpu() was used instead of for_each_possible_cpu(). for_each_possible_cpu() would create very long and useless output. It is still being used for internal buffer, but not for ethtool output. There could be an overflow if cpu was added between ethtool call netvsc_get_sset_count() and netvsc_get_ethtool_stats() and netvsc_get_strings(). (still safe if cpu was removed) ethtool makes these three function calls separately. As long as we use ethtool, I can't see any clean solution. Currently and in foreseeable short term, Hyper-V doesn't support cpu hot-plug. Plus, ethtool is for admin use. Unlikely the admin would perform such combo operations.

2018-07-30ath10k: add debugfs file warm_hw_resetMaharaja Kennadyrajan
Debugfs support to do hardware warm reset with WMI command WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi service is enabled in the firmware for backward compatibility). This change is purely for debugging purpose when hardware hangs/mutes. This hardware reset won't affect the connectivity but there will be small pause in data traffic. Here we are doing BB/MAC level reset and hence whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset. So the target will be in the active state.
