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.

Hi all,
I have here a buggy firewire bridge (Prolific PL3507) which requires that each

How to fix this? Sure one could add a hack to sbp2.c to
