31 * We embed system errno values and OpenFlow standard and vendor extension
32 * error codes into the positive range of "int":
34 * - Errno values are assumed to use the range 1 through 2**30 - 1.
36 * (C and POSIX say that errno values are positive. We assume that they
37 * are less than 2**29. They are actually less than 65536 on at least
38 * Linux, FreeBSD, OpenBSD, and Windows.)
40 * - OpenFlow standard and vendor extension error codes use the range
41 * starting at 2**30 (OFPERR_OFS).
43 * Zero and negative values are not used.
