[dpdk-dev] [PATCH v2 0/7] virtio 1.0 enabling for virtio pmd driver

[Yuanhan Liu <yuanhan.liu@linux.intel.com>]

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.
