One of the prerequisite commits required for this patch to apply to lts- backport-utopic and Trusty(Commit 0b725a2c) was making changes to the igb driver.
I created a new backport of this commit, so it does not touch igb. There was good testing in bug 1492146 with this kernel, see commits 34 -> 37. Can you also test this linux-lts-utopic kernel to see if it resolves this bug? If it does, I'll build a Trusty test kernel for testing. We can then re-submit the SRU request the fixes will no longer cause the regression.

This will help make the host more efficient since it can potentially process a larger batch of packets. Implement this optimization.
