> If less than the expected number of bytes are read then log the

> v2: handle additional rte_pci_read_config incomplete reads
> v3: do not handle rte_pci_read_config of virtio cap, added in v2,
>     as it's less clear what the right thing to do there is
> v4: do a more robust check - first check what the vendor is, and
>     skip the cap entirely if it's not what we are looking for.
> v5: fetch only 2 flags bytes if the vndr is PCI_CAP_ID_MSIX
> v6: fix 32bit build by changing the printf format specifier, fix patch title

Tiwei did a comment on v5 and provided his Reviewed-by.
Is it OK to apply v6 with its tag?
All is fixed?
