I am trying to enable MSI interrupts in em driver on freebsd guest OS, using Qemu e1000 emulation in 0.13.0, but it does not seem to work. After adding MSI support in driver, pci_msi_count() returns 0, which means probably e1000 does not support it in 0.13.0? How can I make e1000 device (or which version) have support for MSI?
