Add support for MSI-X interrupts in the virtio network device and make that
the default.
The current behavior of advertising a single MSI vector can be requested by
setting the environment variable "BHYVE_USE_MSI" to "true". The use of MSI
is not compliant with the virtio specification and will be eventually phased
out.
