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.
