The rate mask is used to tell firmware the supported rate depends on negotiation. We loop 2 times for all VHT/HT 2SS rate mask first, and then only keep the part according to chip's NSS. This commit fixes the logic error of '&' operations for VHT/HT rate, and we should run this logic before adding legacy rate. To access HT MCS map, index 0/1 represent MCS 0-7/8-15 respectively.

2020-01-26rtw88: Add wowlan net-detect supportChin-Yen Lee7-15/+571
Net-detect is an option of wowlan to allow the device to be woken up from suspend mode when configured network is detected. When user enables net-detect and lets the device enter suspend state, wowlan firmware will periodically scan until beacon or probe response of configured networks are received. Between two scans, wowlan firmware keeps wifi chip in idle mode to reduce power consumption. If configured networks are detected, wowlan firmware will trigger resume process.

Pattern match is an option of wowlan to allow the device to be woken up from suspend mode when receiving packets matched user-designed patterns. The patterns are written into hardware cam in suspend flow if users have set up them. If packets matched designed pattern are received, wowlan firmware will get an interrupt and then wake up the device.

2020-01-26rtw88: support wowlan feature for 8822cChin-Yen Lee13-0/+836
Wake on WLAN(wowlan) is a feature which allows devices to be woken up from suspend state through wlan events. When user enables wowlan feature and then let the device enter suspend state, wowlan firmware will be loaded by the driver and periodically monitors wifi packets. Power consumption of wifi chip will be reduced in this state. If wowlan firmware detects that specific wlan event happens, it will issue wakeup signal to trigger resume process. Driver will load normal firmware and let wifi chip return to the original state. Currently supported wlan events include receiving magic packet, rekey packet and deauth packet, and disconnecting from AP.

2020-01-26rtw88: add interface config for 8822cYan-Hsuan Chuang4-0/+27
Some devices need to configure interface/HCI related reigsters in power on flow. Add interface_cfg for HCI for the settings. The driver only supports RTL8822BE/RTL8822CE now, and since RTL8822BE does not need to configure PCIE, the configuration is only added for RTL8822CE. Without it, some of the RTL8822CE device can crash and disconnected to host in suspend/wowlan mode.

2020-01-26mwifiex: drop most magic numbers from mwifiex_process_tdls_action_frame()Brian Norris1-47/+28
Before commit 1e58252e334d ("mwifiex: Fix heap overflow in mmwifiex_process_tdls_action_frame()"), mwifiex_process_tdls_action_frame() already had too many magic numbers. But this commit just added a ton more, in the name of checking for buffer overflows. That seems like a really bad idea. Let's make these magic numbers a little less magic, by (a) factoring out 'pos[1]' as 'ie_len' (b) using 'sizeof' on the appropriate source or destination fields where possible, instead of bare numbers (c) dropping redundant checks, per below. Regarding redundant checks: the beginning of the loop has this: if (pos + 2 + pos[1] > end) break; but then individual 'case's include stuff like this: if (pos > end - 3) return; if (pos[1] != 1) return; Note that the second 'return' (validating the length, pos[1]) combined with the above condition (ensuring 'pos + 2 + length' doesn't exceed 'end'), makes the first 'return' (whose 'if' can be reworded as 'pos > end - pos[1] - 2') redundant. Rather than unwind the magic numbers there, just drop those conditions.

2020-01-12net: ethernet: ixp4xx: Standard module initLinus Walleij1-52/+44
The IXP4xx driver was initializing the MDIO bus before even probing, in the callbacks supposed to be used for setting up the module itself, and with the side effect of trying to register the MDIO bus as soon as this module was loaded or compiled into the kernel whether the device was discovered or not. This does not work with multiplatform environments. To get rid of this: set up the MDIO bus from the probe() callback and remove it in the remove() callback. Rename the probe() and remove() calls to reflect the most common conventions. Since there is a bit of checking for the ethernet feature to be present in the MDIO registering function, making the whole module not even be registered if we can't find an MDIO bus, we need something similar: register the MDIO bus when the corresponding ethernet is probed, and return -EPROBE_DEFER on the other interfaces until this happens. If no MDIO bus is present on any of the registered interfaces we will eventually bail out. None of the platforms I've seen has e.g. MDIO on EthB and only uses EthC, there is always a Ethernet hardware on the NPE (B, C) that has the MDIO bus, we just might have to wait for it.

hclge_reset_prepare_down() is only used to inform VF that PF is going to do function reset, then using hclge_func_reset_sync_vf() in hclge_reset_prepare_wait() to query whether VF is ready before asserting PF function reset.

Currently, the actual work of VF FLR is handled in the reset task, which is asynchronous. So in some case, if the preparing and rebuilding are not done, then the VF FLR will trigger some problems, for example, makes hardware go into chaos. So this patch separates the process of VF FLR from reset task, and adds a semaphore to serialize this reset and others. When FLR's preparing fails, if there has other higher level reset pending or failing times less than the HCLGE_FLR_RETRY_CNT, this preparing should be retried, otherwise it will get into a wrong state. BTW, while the hardware reports misc interrupt during pcie_flr(), the driver can not receive this interrupt anymore, so disable it when hclgevf_flr_prepare() return, and re-enable it when enter hclgevf_flr_done(). Avoid declaring internal function hclgevf_enable_vector(), this patch also moves its definition forward, and removes unused enum hnae3_flr_state.

This file is supposed to contain both the list of generic parameters implemented by the driver, as well as a list of driver-specific parameters and their descriptions. It would also be good if the driver documentation included other driver-specific implementations, such as info versions, devlink regions, and so forth. Convert all of these documentation files to reStructuredText, and rename them to just the driver name. Future changes will include other driver-specific implementations. Each file will contain a table for the generic parameters implemented, as well as a separate table for the driver-specific parameters. Future sections such as for devlink info versions will be added to these files. This avoids creating additional devlink-<feature>-<driver> files for each devlink feature, reducing clutter in the documentation folder.

A few generic devlink parameters have been added, but never documented. Fix that now. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
