Recently, a modification to FC-LS was accepted which allows multi-frame sequences and all vendors have indicated they are interoperable with the change.

* scsi: lpfc: Disable NPIV support if NVME is enabledDick Kennedy2017-10-031-0/+9
| | | | | | | | | | | | | The initial implementation of NVME didn't merge with NPIV support. As such, there are several issues if NPIV is used with NVME. For now, ensure that if NVME is enabled then NPIV is not enabled. Support for NPIV with NVME will be added in the near future.

* scsi: lpfc: Fix oops if nvmet_fc_register_targetport failsDick Kennedy2017-10-031-4/+11
| | | | | | | | | | | | | | | | if nvmet targetport registration fails, the driver encounters a NULL pointer oops in lpfc_hb_timeout_handler. To fix: if registration fails, ensure nvmet_support is cleared on the port structure. Also enhanced the log message on failure.
