DLPI Primitives

Local Management Primitives

style of DLS provider associated with the DLPI stream. The following provider classes are defined.

DL_STYLE1

PPA is implicitly attached to the DLPI stream by opening the appropriate major/minor device number.

DL_STYLE2

DLS user must explicitly attach a PPA to the DLPI stream using DL_ATTACH_REQ.

ATM DLPI only supports DL_STYLE2.

dl_addr_offset

offset of the address that is bound to the associated stream. If the DLS user issues a DL_INFO_REQ prior to binding a DLSAP, the value of dl_addr_len will be 0 and consequently indicate that there has been no address bound.

dl_version

current supported version of the DLPI.

dl_brdcst_addr_length

length of the physical broadcast address. ATM DLPI does not support broadcast addresses and therefore, the value of this field will be zero.

dl_brdcst_addr_offset

not applicable to ATM DLPI.

dl_growth

growth field for future use. The value of this field will be zero.

State

The message is valid in any state in response to a DL_INFO_REQ.

New State

The resulting state is unchanged.
