scsi: hisi_sas: Set protection parameters prior to adding SCSI host

John Garry · martinkpetersen · commit 7bb25a89aad2 · 2019-01-11T21:38:43.000-05:00
Currently we set the protection parameters after calling scsi_add_host() for v3 hw. They should be set beforehand, so make this change. Appearantly this fixes our DIX issue (not mainline yet) also, but more testing required.
