Initialize Controller

Initialize Controller
This command allows the host to specify global configuration parameters, and initializes the controller for use within
a particular system. Configurable parameters include the number of CQE entries, global DMA control parameters, and
possible offboard locations for posting back returned commands. In addition, this command can be used to associate
station addresses with each of the attached ports. The MAC Control IOPB may be used to control particular ports on
the controller. The actual Initialize Controller IOPB points to a table containing the actual initialization values, named
the Controller Initialization Block.
This command must be issued through the Master Command Entry.
