-To-do list:
-
-* merge into drivers/net/wireless/realtek/rtlwifi/rtl8192*
-* clean up function naming
-* Correct the coding style according to Linux guidelines; please read the document
- at https://www.kernel.org/doc/html/latest/process/coding-style.html.
-* Remove unnecessary debugging/printing macros; for those that are still needed
- use the proper kernel API (pr_debug(), dev_dbg(), netdev_dbg()).
-* Remove dead code such as unusued functions, variables, fields, etc..
-* Use in-kernel API and remove unnecessary wrappers where possible.
-* Fix bugs due to code that sleeps in atomic context.
-* Remove the HAL layer and migrate its functionality into the relevant parts of
- the driver.
-* Switch to use LIB80211.
-* Switch to use MAC80211.
-* Switch to use CFG80211.
-* Improve the error handling of various functions, particularly those that use
- existing kernel APIs.

- * In the event that fragmentation is required, the incoming payload is split

- * If encryption is enabled, each fragment payload size is reduced by enough
- * space to add the prefix and postfix (IV and ICV totalling 8 bytes in
- * the case of WEP) So if you have 1500 bytes of payload with ieee->fts set to
- * 500 without encryption it will take 3 frames. With WEP it will take 4 frames
- * as the payload of each frame is reduced to 492 bytes.
