Requests that the data link service (DLS) provider return the current value of the physical address associated with the stream.
The message consists of one
M_PROTO message block, which contains the following
This structure is defined in /usr/include/sys/dlpi.h.
The DL_PHYS_ADDR_REQ primitive requests that the DLS provider return the current value of the physical address associated with the stream.
|dl_primitive||Specifies the DL_PHYS_ADDR_REQ primitive.|
|dl_addr_type||Specifies the requested address. The value is:|
|Valid||The primitive is valid in any attached state in which a local acknowledgment is not pending. For a style 2 DLS provider, this is after a PPA is attached using the DL_ATTACH_REQ provider.|
|New||The resulting state is unchanged.|
|Successful||The DL_PHYS_ADDR_ACK primitive is sent to the DLS user.|
|Unsuccessful||The DL_ERROR_ACK primitive is returned to the DLS user.|
|DL_NOTSUPPORTED||Indicates the primitive is known but not supported by the DLS provider.|
|DL_OUTSTATE||Indicates the primitive was issued from an invalid state.|
|DL_UNSUPPORTED||Indicates the requested address type is not supplied by the DLS provider.|
|DL_SYSERR||Indicates a system error occurred and the provider did not have access to the physical address.|
