Comment 12 for bug 1748408

A colleague found that this seems to be a known issue:

and the fix should be

https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/drivers/net/ethernet/intel/i40e/i40e_txrx.c?id=2b9478ffc550f17c6cd8c69057234e91150f5972

I will try cherry-picking this onto 4.13, not sure why it never seems to have been pulled into the stable branch.

Also not sure why we are still seeing issues with >= 4.14, very likely a completely different issue there, but I think we'll be fine if we get 4.13 fixed for now.
