Are DDP packages unavailable on Windows or is their loading disabled because
reading from PCI config space is not implemented by netuio? In the former
case, please document the reason in commit (and probably in used guide?).
In the latter case, could you instead fix rte_pci_config_read() to return (-1)
on Windows, so that DDP loading automatically fails at reading capabilities?
This would ensure ICE PMD remains portable by compiling all of its code in
every platform.

Yes, loading of external DDP package is not supported on Windows.

Will update the commit message and the ice user guide accordingly in v2.
