So I'll submit it separately. I don't not agree that it is not related, before this series the example output was: MSI1: OKAY - MSI2: OKAY - MSI3: OKAY - MSI4: OKAY - MSI5: OKAY - MSI6: OKAY - MSI7: OKAY - MSI8: OKAY - MSI9: OKAY - MSI10: OKAY - MSI11: OKAY - MSI12: OKAY - MSI13: OKAY - MSI14: OKAY - MSI15: OKAY - MSI16: OKAY - MSI17: NOT OKAY - MSI18: NOT OKAY - MSI19: NOT OKAY - MSI20: NOT OKAY - MSI21: NOT OKAY - MSI22: NOT OKAY - MSI23: NOT OKAY - MSI24: NOT OKAY - MSI25: NOT OKAY - MSI26: NOT OKAY - MSI27: NOT OKAY - MSI28: NOT OKAY - MSI29: NOT OKAY - MSI30: NOT OKAY - MSI31: NOT OKAY - MSI32: NOT OKAY - SET IRQ TYPE TO MSI-X: OKAY - MSI-X1: OKAY - MSI-X2: OKAY - MSI-X3: OKAY - MSI-X4: OKAY - MSI-X5: OKAY - MSI-X6: OKAY - MSI-X7: OKAY - MSI-X8: OKAY - MSI-X9: NOT OKAY - MSI-X10: NOT OKAY - MSI-X11: NOT OKAY - MSI-X12: NOT OKAY - MSI-X13: NOT OKAY - MSI-X14: NOT OKAY - MSI-X15: NOT OKAY - MSI-X16: NOT OKAY So the output matched the suggested values in the documentation. After this series, the documentation still suggests msi == 16 and msi-x == 8, but the example output now shows that there was no failures. So I think it is most consistent to just update the example in the same commit (in this series) that updates the output to show everything as good.
