Subject: [PATCH] iwlwifi: disable the buggy chain extension feature in HW
|
||||
|
||||
This feature has been reported to be buggy and enabled by
|
||||
default. We therefore need to disable it manually.

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.
