This patch set depends the following series: https://lkml.org/lkml/2018/4/10/421 This series aims to add pcitest tool support for MSI-X. Includes new callbacks methods and handlers to trigger the MSI-X interruptions on the EP Designware IP driver. Provides new methods on pci_epf_test driver that allows to set/get EP maximum number of MSI-X entries (similar to set/get MSI methods). Reworks on MSI set/get and triggering methods on EP Designware IP driver to be more generic and flexible. Adds a new input parameter (msix) and replicates the whole MSI mechanism applied to the MSI-X feature on pcitest tool. Also updates the pcitest script with the new test set applied to this new feature.
