Fine-grained Privileges
Starting HP-UX 11i v3, HP DLPI will allow transmission of IP/ARP
frame only for users with PRIV_NETADMIN privilege.
For more information on the fine-grained privileges, see
Fine-grained
Privileges
on page 17.
DL_UNITDATA_IND
Conveys one DLSDU from the DLS provider to the DLS user.
Format
The message consists of one M_PROTO message block containing the
structure shown below, followed by one or more M_DATA blocks
containing at least one byte of data. The amount of user data that may be
transferred in a single DLSDU is limited. This limit is conveyed by the
parameter dl_max_sdu in the DL_INFO_ACK primitive.

Parameters

DL_UNITDATA_IND
dl_dest_addr_length
length of the address of the DLSAP where this DL_UNITDATA_IND
is intended to be delivered.
dl_dest_addr_offset
offset from the beginning of the M_PROTO message block where the
destination DLSAP address begins.
dl_src_addr_length
length of the DLSAP address of the sending DLS user.
