Ideally wake_tx_queue should be used regardless as
it is a requirement for reducing bufferbloat and
implementing airtime fairness in the future.

However some setups (typically low-end platforms
hosting QCA988X) suffer performance regressions
with the current wake_tx_queue implementation.
Therefore disable it unless it is really
beneficial with current codebase (which is when
firmware supports smart pull-push tx scheduling).

I think it's too late to send this to 4.7 anymore (and this due to my
vacation). So I'm planning to queue this to 4.8, but if the feedback is
positive we can always send this to a 4.7 stable release.

Sorry guys, drowned.
So, yes, applying this patch does the job. That is gets me to the
results similar to
https://lists.openwrt.org/pipermail/openwrt-devel/2016-May/041448.html

Going to try latest code on same system...

Can you try increasing the quantum to 1514, and reducing the codel
target to 5ms? (without this patch?)

So it was 1514 already...
