2018-02-27rtlwifi: Fix VHT NSS in RCPing-Ke Shih
NSS is a argument of highest rate in RC, and it occupies bit 4-7 so use ieee80211_rate_set_vht() to fill the values. Since it got correct rate index, we don't need to check chips to assign NSS in set function anymore.

This is merged by Ping-Ke Shih from commit a221cb0911b8 ("staging: rtlwifi: Remove unnecessary parentheses"), and original commit log is reserved below. Remove unnecessary parentheses to comply with preferred coding style for the linux kernel and avoid the following checkpatch's message: 'CHECK: Unnecessary parentheses around'. Credits to checkpatch.

2018-01-08rtlwifi: Remove unnecessary 'out of memory' messageShreeya Patel
This is merged by Ping-Ke Shih from commit 596e0559d61a ("Staging: rtlwifi: Remove unnecessary 'out of memory' message."), and commit log is reserved below. Logging messages that show some type of "out of memory" error are generally unnecessary as there is a generic message and a stack dump done by the memory subsystem. These messages generally increase kernel size without much added value. Problem found by checkpatch.

rate_control_ops structure is only passed as an argument to the function ieee80211_rate_control_{register/unregister}. This argument is of type const, so declare the structure as const. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-06-29rtlwifi: use s8 instead of charArnd Bergmann
Compiling the rtlwifi drivers for ARM with gcc -Wextra warns about lots of incorrect code that results from 'char' being unsigned here, e.g. realtek/rtlwifi/rc.c:113:18: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8188ee/dm.c:1070:22: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192ce/trx.c:54:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192cu/mac.c:601:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192de/trx.c:53:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192ee/phy.c:1268:12: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192se/rf.c:150:20: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8723be/dm.c:877:29: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8723be/phy.c:386:16: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/dm.c:1514:38: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/phy.c:1558:11: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/phy.c:386:24: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/trx.c:55:12: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/stats.c:31:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] This patch changes all uses of 'char' in this driver that refer to 8-bit integers to use 's8' instead, which is signed on all architectures.

2016-03-08rtlwifi: Fix size of wireless mode variableLarry Finger
Smatch reports the following warning: CHECK drivers/net/wireless/realtek/rtlwifi/rc.c drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)' This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning from ieee80211_get_tx_rates() when using 5G") now checks the wireless mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series(). As a result, all quantities used to store the wireless mode must be u16. This patch also reorders struct rtl_sta_info to save a little space.

2015-10-14rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
