2018-04-30mwifiex: fix mwifiex_hard_start_xmit()'s return typeLuc Van Oostenryck
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'.

2018-04-26iwlwifi: mvm: set wakeup filters for wowlan "any" configurationEliad Peller
In case of "any" wowlan trigger is configured, no valid wakeup filter was configured. Moreover, the fw assumes there's no connection when there are no configured wakeup filters. This leads to the station info not being updated on D3 command, causing rate_n_flags to be 0 when the offloading code sends tx frame (triggering SYSASSERT_102C due to invalid antenna param) Note: "any" trigger is currently assumed to only be used when entering d0i3 (which has a different flow). However, we still reach this code when using d3_test. Signed-off-by: Eliad Peller <eliadx.peller@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2018-04-26iwlwifi: make bitfield a u32 instead of u16Luca Coelho
The bitfield we use in struct iwl_cfg contains 17 bits, but we declare it as u16. The compiler doesn't seem to have any problems with that (it probably automatically makes it u32), but it's cleaner to use a type that is long enough for all the flags. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-04-26iwlwifi: pcie: remove non-responsive deviceLuca Coelho
If we fail to to grab NIC access because the device is not responding (i.e. CSR_GP_CNTRL returns 0xFFFFFFFF), remove the device from the PCI bus, to avoid any further damage, and to let the user space rescan. In order to inform the userspace that a rescan is needed, we send a kobject uevent with "INACCESSIBLE". This functionality is disabled by default, but can be enabled via a new module parameter called "remove_when_gone". In the future we may change this module parameter to include 3 modes instead: do nothing; auto-rescan or; send uevent.

2018-04-26iwlwifi: fw: combine loading of last page block into main copy loopLuca Coelho
Now that we check and copy only the actual size of the page block, there is no need to treat the last block separately. Remove the mostly duplicate code and make the main copy loop handle also the last block. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2018-04-26iwlwifi: fw: harden page loading codeLuca Coelho
The page loading code trusts the data provided in the firmware images a bit too much and may cause a buffer overflow or copy unknown data if the block sizes don't match what we expect. To prevent potential problems, harden the code by checking if the sizes we are copying are what we expect. Cc: stable@vger.kernel.org Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2018-04-26iwlwifi: pcie: allow sending pre-built A-MSDUsEliad Peller
In case of A-MSDUs, the trans layer is taking care of building the subframes (out of the given skb), according to the given gso_size. However, in some testing flows, we want to build the whole A-MSDU frame in a different place (e.g. userspace), and ask the driver to send it as-is. In case of gso_size==0, simply treat the frame as normal-frame, although the A-MSDU flag is set.

2018-04-26iwlwifi: cfg: remove unnecessary cfg data in non-dvm devicesLuca Coelho

2018-04-26iwlwifi: introduce Image Loader (IML) - new firmware imageGolan Ben-Ami
In future devices a new image will be introduced - IML. The IML, image loader, is loaded by the ROM, and as part of the new self-init flow, loads the rest of the firmware images to the device.

2018-04-26iwlwifi: allow different csr flags for different device familiesGolan Ben Ami
Different device families may have different flag values for passing a message to the fw (i.e. SW_RESET).

2018-04-24mt76: rework tx power handlingFelix Fietkau
There were a number of issues in the existing tx power handling code: 1. The EEPROM target power for chain 0 refers to the actual output power after the channel and bandwidth delta have been added to the initial channel gain. This means the delta values should not be added/subtracted for the rate power calculation 2. When power is reduced significantly, the initial channel gain underflows very quickly, while the per-rate power offsets are high. This miscalculation causes effective tx power to be increased when it should actually be lowered. Fix this by trying to adjust the channel gain to the lowest power from the rate table. In case of under- or overflow, compensate by adding an appropriate delta to the rate power values. This makes power configuration more accurate on a wider range of configurable values Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
