Members

dl_primitive: Must be the manifest constant DL_BIND_REQ_T
dl_sap: Specifies data link service access point (SAP), set to the 2-byte Ethernet packet type. Type 0xFFFE signifies all 802.3 packets. Type 0xFFFF signifies all Novell® IPX 802.3 packets. All other types are interpreted as Ethernet packets.
dl_max_conind: Ignored.
dl_service_mode: Specifies service mode; only DL_CLDLS supported.
dl_conn_mgmt: Ignored.
dl_xidtest_flg: Ignored.

DL_BIND_ACK_T

typedef struct {
    ULONG dl_primitive;
    ULONG dl_sap;
    ULONG dl_addr_length;
    ULONG dl_addr_offset;
    ULONG dl_max_connid;
    ULONG dl_xidtest_flg;
} dl_bind_ack_t;

Members

dl_primitive: Must be the manifest constant DL_BIND_ACK_T.
dl_sap: Specifies the SAP from the previous dl_bind_req_t structure.
dl_addr_length: Specifies length of address; always 6.
dl_addr_offset: Specifies offset to address.
dl_max_connid: Specifies maximum connection ID; always 0.
dl_xidtest_flg: Specifies flag for exchange ID test; always 0.

DL_UNITDATA_REQ_T

typedef struct {
    ULONG     dl_primitive;
    ULONG     dl_dest_addr_length;
    ULONG     dl_dest_addr_offset;

} dl_unitdata_req_t;

Members

dl_primitive

Must be the manifest constant DL_UNITDATA_REQ_T

dl_dest_addr_length

Specifies length of destination address; must be 8.

dl_dest_addr_offset

Specifies offset to byte sequence below. The offset must point to a byte sequence composed of the destination media-access control address followed by the Ethernet type.

media-access control address: 6 bytes
type: 2 bytes

dl_priority

Specifies data link priority.

DL_UNITDATA_IND_T

typedef struct {
    ULONG     dl_primitive;
    ULONG     dl_dest_addr_length;

    ULONG     dl_src_addr_offset;
    ULONG     dl_group_address;
} dl_unitdata_ind_t;

Members

dl_primitive

Must be the manifest constant DL_UNITDATA_IND_T.

dl_dest_addr_length

Specifies length of destination address; always 6.

dl_dest_addr_offset

Specifies offset to destination address.

dl_src_addr_length

Specifies length of source address; always 8.

dl_src_addr_offset

Specifies offset to byte sequence below. The offset points to the byte sequence composed of the source media-access control address followed by the Ethernet type.

media-access control address: 6 bytes
type: 2 bytes

dl_group_address

Specifies group address; 1 if broadcast or multicast.
