Subject: [PATCH] iwlwifi: don't mess up the SCD when removing a key
|
|
|
|
When we remove a key, we put a key index which was supposed
|
|
to tell the fw that we are actually removing the key. But
|
|
instead the fw took that index as a valid index and messed
|
|
up the SRAM of the device.
|
|
|
|
This memory corruption on the device mangled the data of
|
|
the SCD. The impact on the user is that SCD queue 2 got
|
|
stuck after having removed keys.
|
|
The message is the log that was printed is:
|
|
|
|
Queue 2 stuck for 10000ms
|
|
|
|
This doesn't seem to fix the higher queues that get stuck
|
|
from time to time.
