Yes. This patch has to be to reverted. It changes the existing interrupt behavior and does not address the MSIX case as well.
I think, The clean fix would be to introduce rte_intr_mask() and rte_intr_unmask() by abstracting the INTX and MSIX differences
And let qede driver call it as needed.
Thoughts?
