This one is against 4.9 -

I assume you'd be interested in applying a fix to all currently maintained 
stable branches between 3.6 to 4.11, per
https://www.kernel.org/category/releases.html .

I know of at least one other person whose workaround has been to disable GRO, 
but I don't understand the networking code well enough to guarantee that
disabling GRO means the problem will never occur under all possible error 
conditions. If it's guaranteed that disabling GRO will definitely mitigate
the bug, probably it's better to stop supporting GRO for these versions of the 
driver instead of trying to implement some other fix.
