An invention is disclosed for a layer structure that facilitates configuring a Fiber Channel driver. In one embodiment, the layer structure includes a hardware layer directory that includes code for communicating with a Fiber Channel controller. In addition, a wrapper layer directory is included in the layer structure. The wrapper layer directory includes code for communicating with the code associated with the hardware layer directory, and also includes a wrapper header file that defines a particular value setting in a first state, such as a compiler directive set a particular value. The layer structure further includes a global header directory that defines a group of value settings. The group of value settings is defined for the code associated with each of the hardware directory and the wrapper layer directory. The particular value setting in the first state is also included in the group of value settings. The code associated with each of the hardware layer directory, the wrapper layer directory and the global header directory is linked with one another. The linking is accomplished such that any change to the particular value setting made in the code associated with the wrapper layer directory has priority over the first state defined in the global header directory.
