Chapter 2 DLPI Primitives Local Management Primitives The message is valid in any State in which a local acknowledgment is not pending, as described in Appendix B, Allowable Sequence of DLPI Primitives, of the DLPI 2.0 specification. New State The resulting state is unchanged. Response The DLPI driver responds to this request with a DL_HP_PPA_ACK. DL_HP_PPA_ACK This primitive is sent in response to a DL_HP_PPA_REQ; it conveys information on each valid PPA currently installed in the system. This message consists of one M_PCPROTO message block, which contains the following structure and information: Format typedef struct { u_long dl_primitive; u_long dl_length; u_long dl_count; u_long dl_offset; } dl_hp_ppa_ack_t; Parameters dl_primitive DL_HP_PPA_ACK dl_length length of the data area following the DL_HP_PPA_ACK primitive. The data area is formatted as one or more dl_hp_ppa_info_t structures. dl_count number of PPAs in the list. dl_offset offset from the beginning of the M_PCPROTO block where the dl_hp_ppa_info_t information begins. 59
