[PATCH rtw-next 5/5] wifi: rtlwifi: rtl8192d: let the firmware use all rates
From: Ho Jie Feng
Date: Tue Nov 03 2026 - 05:16:41 EST
The rate mask is chosen based on rssi_level, however rssi_level
is always 0, since:
- for rtl8192de, call to rtl92d_dm_refresh_rate_adaptive_mask is
commented out and function is not implemented
- for rtl8192du, it is also not called.
This makes the branch always choose less than optimal allowed MCS rates.
Enable all the rates.
Test results (2.4 GHz):
before after
TX 6.4 12.6
RX 32.0 39.1
