41 * To allow for future enhancements to extend the tunables
42 * add a hdr to this structure, so that the version can be set
43 * and checked for backwards compatibility. Newer versions of LNet
44 * can still work with older versions of lnetctl. The restriction is

47 * fields must remain the same, and new fields appended to the structure
49 * That said all existing LND tunables will be added in this structure
50 * to avoid future changes.
