Subject: [PATCH 2/2] wifi: rtl8xxxu: Fix off by one initial RTS rate
|
||
|
|
|
||
|
|
rtl8xxxu_set_basic_rates() sets the wrong initial RTS rate. It sets the
|
||
|
|
next higher rate than the one it should set, e.g. 36M instead of 24M.
|
||
|
|
|
||
|
|
The while loop was supposed to find the index of the most significant
|
||
|
|
bit which is 1, but it was copied incorrectly from the vendor driver.
|
||
|
|
Use __fls() instead.
