+Subject: [PATCH] lpfc: Fix port initialization failure
+References: bsc#1093290
+Patch-Mainline: submitted linux-scsi 2018/05/25
+
+The driver exits port setup after failing the
+lpfc_sli4_get_parameters command (messages 0356, 2541, & 1412).
+
+The older CNA adapters do not support the MBX command. In the past
+the code was allowed to fail and continue on with initialization.
+However a nvme change moved a closing bracket and now makes all
+failures terminal.
+
+Revise the logic so that terminal failure only occurs if the command
+failed on the newer adapters. Additionally, if parameters are set
+that require information from the command and the command failed,
+the parameters are erroneous and port set up should fail even on
+the older adapters.
