Can you show me a sample code (if_em.c?). Thanks.

PCI-Express devices must support MSI or MSI-X, but that doesn’t mean an OS has to implement MSI(-X) to support PCIe devices. Many PCIe devices also emulate the legacy interrupt mode and thus can work with drivers and OS that know nothing about PCIe or MSI(-X).
