Subject: [PATCH 092/102] net-next: mediatek: remove superfluous queue wake up
|
|
call
|
|
|
|
The code checks if the queue should be stopped because we are below the
|
|
threshold of free descriptors only to check if it should be started again.
|
|
If we do end up in a state where we are at the threshold limit, it makes
|
|
more sense to just stop the queue and wait for the next IRQ to trigger the
|
|
TX housekeeping again. There is no rush in enqueuing the next packet, it
|
|
needs to wait for all the others in the queue to be dispatched first
|
|
anyway.
