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.
