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.
46 #define OFPERR_OFS (1 << 30)
48 /* OpenFlow error codes.
50 * The comments below are parsed by the extract-ofp-errors program at build
51 * time and used to determine the mapping between "enum ofperr" constants and
52 * error type/code values used in the OpenFlow protocol:
54 * - The first part of each comment specifies OpenFlow type/code for each
55 * protocol that supports the error.
57 * - Additional text is a human-readable description of the meaning of each
58 * error, used to explain the error to the user. Any text enclosed in
59 * square brackets is omitted; this can be used to explain rationale for
60 * choice of error codes in the case where this is desirable. */
