HSC FDDI Driver
HP-UX 11i includes code that enhances the HSC FDDI driver. These driver
modifications increase performance of the FDDI link by up to 20%.
The performance enhancement was done by making the driver MBLK-based, whereas
previously it was MBUF-based. Other code-path and function-call reductions have
further improved performance and scalability. These changes are not directly visible to
the user and have no effect on current documentation or support.
