[ipxe-devel] [PATCH 0/4] Implement virtio 1.0 support

[Ladi Prosek]

The goal here is to support booting from modern only (non-transitional)
virtio-net devices. The code strives to comply with the virtio 1.0 spec
and is heavily inspired by the Linux kernel implementation.

One notable divergence from Linux is the explicit differentiation
between port I/O and memory I/O due to the lack of __iomem in iPXE. See
struct virtio_pci_region for details.
