[PATCH] staging: rtl8723bs: cleanup and style fixes

 TODO:
-- Partial: remove remaining code for other chips that is left over. Unused
-  non-8723B AMPDU burst enum values and unused 8188E ODM fields have been
-  removed, but more legacy code remains.
-- Partial: convert unusual variable types. The channel control APIs and rate
-  helpers now use kernel fixed-width types, but more legacy types remain.
-- Partial checkpatch.pl fixes: several overlong callback and scan-list lines
-  have been wrapped, but many warnings remain and will require refactoring.
-- Merge Realtek's bugfixes and new features into the driver.
-- Switch to use MAC80211.
+- Partial: remove remaining code for other chips that is left over. Removed
+  obsolete 8192C receive code, unused multi-chip constants, and an old 88C
+  firmware exception; more compatibility code remains.
+  
+- Partial: convert unusual variable types. The rate-set length helper now uses
+  kernel fixed-width types; channel-control APIs and more legacy types remain.
+
+- Partial checkpatch.pl fixes: the scan callback and scan-list operations have
+  been wrapped and simplified, but many warnings remain and will require
+  refactoring.
+
+- Merge Realtek's bugfixes and new features into the driver. This needs a
+  specific upstream commit or feature target before it can be reviewed safely.
+
+- Switch to use MAC80211. This requires replacing the vendor-owned netdev,
+  cfg80211 operations, MLME, Ethernet TX/RX conversion, and TX completion
+  paths with mac80211 ownership; do not register a second wiphy/netdev until
+  the station-mode TX/RX path has been ported.
