zfcp has a couple of definitions to describe the FC protocol. Grepping through the complete source tree shows that e.g. the lpfc module makes similar private definitions. It think that it would make sense to introduce a global header file for FC related definitions that each FC driver can use.
The attached patch contains some definitons that i found in zfcp and could be reused by other drivers. What do others think? Would this be useful?
