- Correctly refresh Rx filter when AP (IBSS) vap is created after STA vap. - Block any RCR updates during TSF correction (IBSS mode). - Set CBSSID* bits during vap creation, not when it was started / stopped. - Cache current state to prevent unnecessary register reads. Tested with RTL8188CE, STA + AP mode.
