If anyone has any objections, please let me know. ------------------ From: Manikanta Pubbisetty [ Upstream commit f78210dd4bea09090b828adc2733cad4b9916306 ] When an error occurs during RX packet processing (e.g., MSDU done failure), the driver sets rx_confused and drops all subsequent RX packets until a Wi-Fi ON/OFF cycle clears the flag. This can leave the device in a bad state where it cannot process RX data traffic. Instead of leaving the device in such a state, trigger hardware recovery so that such an error state can be reset and the device can function again normally.
