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 structure:
typedef struct
{
ulong dl_primitive;
ulong dl_addr_type;
} dl_phys_addr_req_t;
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:

Item | Description |
---|---|
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. |
Item | Description |
---|---|
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. |
Item | Description |
---|---|
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. |
