This breaks cross-compilation because devpropdef.h is all-lowercase on Linux.

Why return (-1) in one case and ERROR_NOT_SUPPORTED in another if these cases
are not distinguished by the caller? Also, it returns 0 on success, but
caller checks for ERROR_SUCCESS (which is 0, but this is inconsistent).

Sorry for nitpicking, but such alignment hurts readability, with 8 spaces
per tab, at least. Please consider using spaces in the middle of line.

RTE_LOG() does output, which may rewrite GetLastError(), consider swapping
these two lines.
