HP DLPI Features
Hewlett-Packard’s implementation of the Data Link Provider Interface,
HP DLPI, conforms to the DLPI Version 2.0 Specification as a Style 2
provider. HP DLPI offers data link service users:
• Clone (maximum 900) and non-clone (maximum 100) access.
• Support for Ethernet/IEEE802.3, FDDI, Fibre Channel, 100VG and
Token Ring.
• Support for connectionless and connection-mode services
(connection-mode services are supported only over IEEE802.3 and
Token Ring).
• Also support for raw-mode services. For details on raw mode, see the
DL_BIND_REQ, DL_HP_RAW_REQ and DL_HP_RAW_IND
primitives. Raw mode is supported on Ethernet/802.3, FDDI, Token
Ring, Fibre Channel and 100VG.
• Style 2.
• I_STR ioctl is supported for doing device-specific control/diagnostic
requests.
• Priority messages are supported over 100VG (see
DL_UNIT_DATA_REQ primitive).
• For support of third-party devices, refer to the third-party user
manuals.
• Support for the following HP products: Ethernet/IEEE802.3, FDDI,
Fibre Channel, 100VG and Token Ring.
• The following devices support all levels of promiscuous mode: NIO
ethernet LAN, J2146A (HP-PB) NIO LAN only (the 36967A-20N
(HP-PB) card is NOT supported), CIO ethernet LAN driver, Series
700 core and HP EISA LAN. For support of third-party devices, refer
to the third-party user manuals.
NOTE The HP ATM adapter provides its own “native” DLPI provider, which
should not be confused with this DLPI provider.
HP DLPI does not currently include:
• Quality of Service (QOS) management.
