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
