The latest thread for this topic was:

https://www.spinics.net/lists/netdev/msg757787.html

with the last message of the thread being:

https://www.spinics.net/lists/netdev/msg765710.html

But I don't think it has been submitted.

If I'm not wrong, the babble issue will probably also require a
follow-up patch to change the default rx urb size for the scenario
without qmap.

Daniele
