wifi: rtw89: coex: only read Bluetooth counter of report version 1 for RTL8852A
|
||
|
|
|
||
|
|
Only when firmware control report version is 1, need to get the counter by
|
||
|
|
reading the register. The other version will monitor the counter at
|
||
|
|
firmware. And upstream branch only RTL8852A has this old version.
