HP-UX 11i Version 2 Release Notes (October 2003)

Internet and Networking
HP-UX Data Link Provider Interface (DLPI)
Chapter 6
127
— <sio/dlpi_drv.h>
• Clarifications of subsys errors for primitives to provide more specific error status.
• Obsolescence of the dump read capability of lanscan.
• The Network Tracing and Logging (NetTL) facility logging for customers and
internal tracing.
NOTE VLAN functionality is not supported in HP-UX 11i v2.
Impact
• Enhancements to the Streams interface provide a richer feature set for network
stack feature options. This includes the options negotiations mechanism between
the DLS user/application and the underlying drivers. This will impact existing IP
Stream modules requiring recode and recompile.
• Third-party driver writers can take advantage of the non-native driver interfaces for
their drivers.
• Third-party driver writers supporting their own native models can now hook more
easily into the lanscan tool.
• With consolidation through obsoleting, deprecating, and adding new header files,
comes a clean-up of obsolete declarations and a division of application and driver
required structures.
• Clarifications of subsys errors for primitives provide more specific error status.
• The dump read capability of lanscan has been obsoleted.
• With status logging for DLPI through nettl, customers are provided additional
information for events, as well as internal logging and tracing for engineering
internal support.
Compatibility
• Kernel IP Stream modules that previously used options or fastpath negotiation
features, or that looked into network data packets in previous versions, must make
changes and recompile for HP-UX 11i v2.
• While third-party driver writers can now write non-native drivers, native driver
writers will need to make changes if they want to interact with HP's lanscan
command. This would require recoding and recompiliation.
• Driver writers will need to recode and recompile with the new included files, and will
need to remove references to obsoleted include files.
• Applications that are interested in subsys errors for primitive calls will need to
recode and recompile.
Performance
There are no performance issues.
