[PATCH V2 00/11] net: mediatek: various small fixes

[John Crispin]

This series contains various small fixes that we stumbled across while
doing thorough testing and code level reviewing of the driver. The only
patch that sticks out is the first one, which addresses a DQL related
issue. The rest are just minor fixes.

Changes in V2:
* drop the DQL patch from the list until a better solution is found

[PATCH V2 01/11] net: mediatek: add missing return code check

[John Crispin]

The code fails to check if the scratch memory was properly allocated. Add
this check and return with an error if the allocation failed.

[PATCH V2 02/11] net: mediatek: fix missing free of scratch memory

[John Crispin]

Scratch memory gets allocated in mtk_init_fq_dma() but the corresponding
code to free it is missing inside mtk_dma_free() causing a memory leak.
With this patch applied, we can run ifconfig up/down several thousand
times without any problems.

[PATCH V2 03/11] net: mediatek: invalid buffer lookup in mtk_tx_map()

[John Crispin]

The lookup of the tx_buffer in the error path inside mtk_tx_map() uses the
wrong descriptor pointer. This looks like a copy & paste error. Change the
code to use the correct pointer.

[PATCH V2 05/11] net: mediatek: add next data pointer coherency protection

[John Crispin]

The QDMA engine can fail to update the register pointing to the next TX
descriptor if this bit does not get set in the QDMA configuration register.
Not setting this bit can result in invalid values inside the TX rings
registers which will causes TX stalls.

[PATCH V2 06/11] net: mediatek: disable all interrupts during probe

[John Crispin]

The current code only disables those IRQs that we will later use. To
ensure that we have a predefined state, we really want to disable all IRQs.
Change the code to disable all IRQs to achieve this.

[PATCH V2 07/11] net: mediatek: fix threshold value

[John Crispin]

The logic to calculate the threshold value for stopping the TX queue is
bad. Currently it will always use 1/2 of the rings size, which is way too
much. Set the threshold to MAX_SKB_FRAGS. This makes sure that the queue
is stopped when there is not enough room to accept an additional segment.

[PATCH V2 08/11] net: mediatek: increase watchdog_timeo

During stress testing, after reducing the threshold value, we have seen
TX timeouts that were caused by the watchdog_timeo value being too low.
Increase the value to 5 * HZ which is a value commonly used by many other
drivers.

[PATCH V2 11/11] net: mediatek: remove superfluous queue wake up call

[John Crispin]

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.

What do you mean it won't end up in the GIT history?  I always put this
introductory text into the merge commit for the patch series.

Now, I can remove it for you, which I will do.
