But just as a counterexample to that: qla2xxx and lpfc are both capable of driving a wide range of chip generations and firmware interface versions with a single driver. The problem I have with the mpt2sas/mpt3sas split is that there are way more commonalities than there are differences. It is trivial to handle multiple scatterlist format and features in a single driver. You guys already do that in megaraid_sas. -- Martin K.
