Sorry, yes.  It is current in 3.16.y, and we would like it queued up for
3.14.y and 3.15.y stable trees.  I got a bit confused when I went to
submit this to stable and saw that networking stable patches were
handled differently that other stable patches.  I tried to make my
request clear by writing that first paragraph in the patch description,
but I probably just muddied the water instead.

It is just easier, when the developers tell me to begin with that a
patch needs to go into stable when they first submit the patch.  Which
was not the case for this patch, grrr.
