DIX is supported in mpt3sas , but not by default and hence while loading mpt3sas driver set module parameter "prot_mask=0x7F" to enable DIX support.

I am a Ph.D student of University of Minnesota, Twin Cities. Recently, I am working on a project of T10 PI-capable MD module. However, I fail to use DIX with the HBA/driver combination of LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02) /mpt3sas even though I have formatted the drives with DIF protection type 1. May I know if DIX (data integrity extension) is supported in mpt3sas driver?
