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