Subject: [PATCH] scsi: lpfc: Correct topology type reporting on G7 adapters
Git-commit: 76558b25733140a0c6bd53ea8af04b2811c92ec3
Patch-mainline: v5.0-rc1
References: bsc#1118215
Driver missed classifying the chip type for G7 when reporting supported
topologies. This resulted in loop being shown as supported on FC links that
are not supported per the standard.
Add the chip classifications to the topology checks in the driver.
