  33  *
  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.)
  39  *

  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:
  53  *
  54  *   - The first part of each comment specifies the vendor, OpenFlow versions,
  55  *     type, and sometimes a code for each protocol that supports the error:
  56  *
  57  *         # The vendor is OF for standard OpenFlow error codes.  Otherwise it
  58  *           is one of the *_VENDOR_ID codes defined in openflow-common.h.
  59  *
  60  *         # The version can specify a specific OpenFlow version, a version
  61  *           range delimited by "-", or an open-ended range with "+".
  62  *
  63  *         # Standard OpenFlow errors have both a type and a code.  Extension
  64  *           errors generally have only a type, no code.  There is one
  65  *           exception: Nicira extension (NX) errors for OpenFlow 1.0 and 1.1
  66  *           have both a type and a code.  (This means that the version
  67  *           specification for NX errors may not include version 1.0 or 1.1 (or
  68  *           both) along with version 1.2 or later, because the requirements
  69  *           for those versions are different.)
  70  *
  71  *   - Additional text is a human-readable description of the meaning of each
  72  *     error, used to explain the error to the user.  Any text enclosed in
  73  *     square brackets is omitted; this can be used to explain rationale for
  74  *     choice of error codes in the case where this is desirable. */
