3.2.2 Description
The LSIFC929 controller operates in an environment where one or more
host drivers serve as the interface layer between the operating system
and the Fusion-MPT services provided by the LSI Logic Fibre Channel
firmware. The host driver is responsible for initializing the controller,
building request message frames, issuing request message frames to the
controller, and processing reply message frames received from the
controller.
The LSI Logic firmware translates Fusion-MPT message frames into
Fibre Channel specific sequences, frames, and primitives that are
delivered to the Fibre Channel transmit and receive physical interfaces.
The firmware-based Link Services library provides all link service support
used by the host for all FC topologies, transparently. The firmware also
