* wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple driversAndrew Zaborowski2017-03-063-0/+6
| | | | | | | | | | | | | | Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

* scripts/spelling.txt: add "aligment" pattern and fix typo instancesMasahiro Yamada2017-02-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | Fix typos and add the following to the scripts/spelling.txt: aligment||alignment I did not touch the "N_BYTE_ALIGMENT" macro in drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable impact. I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because it is surrounded by #if 0 ... #endif. It is surely safe and I confirmed "_alignment_handler" is correct. I also fixed the "controler" I found in the same hunk in arch/openrisc/kernel/head.S.

| * | rtlwifi: rtl8192cu: Convert driver to use common macrosLarry Finger2017-01-202-163/+132Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These drivers use a set of complicated macros to extract and insert information for the RX and TX descriptors. Driver rtl8192cu had a different set than was used for the PCI-based drivers. To simplify the code, rtl8192cu is switched to use the common version. In the process, two errors in those common macros were found and fixed. Besides simplifying the code, there is an additional benefit. We have no BE hardware to test the PCI driver, but using the common macros provides an additional test for the validity of many endian-sensitive operations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver requires a checksum for the descriptors so that the wifi chip is assured that the USB transmission was correct. These entries are little-endian, but the driver was always using cpu order in the calculation. As a result, the driver failed on BE hardware.

| * | rtlwifi: Download firmware as bytes rather than as dwordsLarry Finger2017-01-209-381/+85Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware is read from disk as a little-endian byte string. The code that loads the firmware into the device transfers it as 4-byte quantities. The routines that write multi-byte quantities on BE hardware assume that the data are in CPU order, and automatically do the conversion to the LE order required by the device. As a result, the firmware is transmitted incorrectly. Rather than do multiple byte swaps on the data, the download routine is revised to transmit bytes rather than dwords. Although the number of I/O operations is increased, the firmware is not often loaded. All drivers have the same bug, and use essentially the same code to download firmware. These routines have been moved into rtlwifi. Some CamelCase variables have been renamed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the kernel provides access to module parameters through entries in /sys/module/<driver>/parameters/, there is no need for a private interface. Thus the existing code for setting the debug level is removed.

| * | rtlwifi: Convert COMP_XX entries into a proper debugging maskLarry Finger2017-01-2015-105/+70Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The debugging macros contain a parameter COMP_XX that could be used as a mask; however, the code turns all these various bits on at the same time. This change implements them as a proper mask, and adds module parameters to set the mask at load time. The current name "debug" for the debug level has been changed to "debug_level" to better differentiate it from "debug_mask". The debug routines have also been changed to interrogate the structure that is loaded at entry time. As a result, the structure rtl_debug is no longer needed, and all references to it are deleted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The addresses of Wlan NIC registers are natural alignment, but some drivers have bugs. These are evident on platforms that need natural alignment to access registers. This change contains the following: 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI, thus it should use rtl_read_byte(). 2. Register 0x4C7 of 8192ee is single byte.
