The Realtek rtl8188ctv (0x0bda:0x018a) is a highly integrated single-chip WLAN USB2.0 network interface controller. Currently rtl8188ctv is supported by rtlwifi driver. It is similar to the rtl8188cus(0x0bda:0x818a) and uses the same config. Signed-off-by:

Enable the use of CQM_RSSI_LIST with mt76-devices. The change has been tested with the mt7602, mt7603 and mt7621 PCI wifi-cards. I passed a list of RSSI thresholds to the driver, and when disconnecting/connecting the antenna(s) I got an event each time the RSSI went above/below a threshold. While I have not been able to test the change with any of the mt76 USB-devices (no access to a device), the RX RSSI management code is shared between the two device types. Thus, CQM should also work with the mt76 USB-devices. Signed-off-by:

While running regressions, observed below kernel panic when sdio disconnect called. This is because of, kthread_stop() is taking care of wait_for_completion() by default. When wait_for_completion triggered in kthread_stop and as it was done already, giving kernel panic. Hence, removing redundant wait_for_completion() from rsi_kill_thread(). ... skipping ...

During testing in ARM32 platforms, observed below kernel panic, as driver accessing data beyond the allocated memory while submitting URB to USB. Fix: Resolved this by specifying correct length by considering 64 bit alignment. so that, USB bus driver will access only allocated memory. Unit-test: Tested and confirm that driver bring up and scanning, connection and data transfer works fine with this fix. ...skipping...
