+Subject: [PATCH] rtl8xxxu: Fix rtl8723bu driver reload issue
+
+The generic disable_rf() function clears bits 22 and 23 in
+REG_RX_WAIT_CCA, however we did not re-enable them again in
+rtl8723b_enable_rf()
+
+This resolves the problem for me with 8723bu devices not working again
+after reloading the driver.
