66  *  - DLADM_OPT_FORCE:
67  *    The function requests to execute a specific operation forcefully.

72  *  - DLADM_OPT_VLAN:
73  *    Signifies VLAN creation code path
74  *
75  *  - DLADM_OPT_NOREFRESH:
76  *    Do not refresh the daemon after setting parameter (used by STP mcheck).
77  *
78  *  - DLADM_OPT_BOOT:
79  *    Bypass check functions during boot (used by pool property since pools
80  *    can come up after link properties are set)
81  *
82  *  - DLADM_OPT_TRANSIENT:
83  *    Indicates that the link assigned to a zone is transient and will be
