Subject: [PATCH] rtl8xxxu: Fix rtl8192eu driver reload issue
|
|
|
|
The 8192eu suffered from two issues when reloading the driver.
|
|
|
|
The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and
|
|
23 didn't get set in rtl8192e_enable_rf().
|
|
|
|
In addition it also seems prone to issues when setting REG_RF_CTRL to
|
|
0 intead of just disabling the RF_ENABLE bit. Similar to what was
|
|
causing issues with the 8188eu.
|
|
|
|
With this patch I can successfully reload the driver and reassociate
|
|
to an APi with an 8192eu dongle.
