2024-02-15wifi: rtlwifi: rtl8192cu: Fix 2T2R chip type detectionBitterblue Smith
rtl8192cu handles 1T1R devices (RTL8188CUS), 1T2R devices (RTL8191CU), and 2T2R devices (RTL8192CU). The 2T2R devices were incorrectly detected as 1T2R because of a mistake in the IS_92C_1T2R macro. The visible effect of this is that the firmware was allowed to use TX rates only up to MCS7. Fix the IS_92C_1T2R macro. Now my 2T2R device has much better upload speed. Before: 46 Mbps. After: 82 Mbps. Also fix a debug message which was printing "RF_1T1R" even for 1T2R chips.

2019-09-03rtlwifi: rtl8192cu: Convert inline routines to little-endian wordsLarry Finger
In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine.

2019-09-03rtlwifi: rtl8192cu: Convert macros that set descriptorLarry Finger
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast and other warnings are fixed.

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.
