Comment 2 for bug 1713553

Note there is one additional upstream commit that improves performance by allowing up to 12k per tx descriptor, instead of 8k per descriptor (the current code in Xenial 4.4 kernel), and its changes are related to the fixes for this issue. However, from my reading of the code, I don't think that commit is actually required to fix this problem, so I am not including it in this bug (yet).
