Yes you're right, patch 1 is also a fix and patch 4 seems to solve other
issues. However, patch 4 makes also some refactoring and seems a bit risky.
We need an ixgbe maintainer to decide wether we can merge it before the
release. Or is it possible to have fixes of the patch 4 without the
refactoring?

Thanks Vlad.
Sorry to request such split but this PMD is sensible and I don't want to
have a risk of making it worst in release 2.0.
