v2: - fix a data corruption reported by Qian, due to hdr size mismatch.
check detailes at ptach 5.
- Add missing config_irq and isr reading support from v1.
- fix comments from v1.
Almost all difference comes from virtio 1.0 are the PCI layout change:
the major configuration structures are stored at bar space, and their
location is stored at corresponding pci cap structure. Reading/parsing
them is one of the major work of patch 7.
To make handling virtio v1.0 and v0.95 co-exist well, this patch set
introduces a virtio_pci_ops structure, to add another layer so that
we could keep those vtpci_foo_bar "APIs". With that, we could do the
minimum change to add virtio 1.0 support.
