From f6c5e6c4561d2a94a8eb39e6d4cb87a715bbd3de Mon Sep 17 00:00:00 2001 From: James Smart Date: Thu, 22 Jul 2021 15:17:18 -0700 Subject: [PATCH] scsi: lpfc: Revise Topology and RAS support checks for new adapters Support for Topology and RAS logging capabilities were qualified by PCIe device ID checks necessitating additional driver changes for new device IDs. Reduce reliance on specific PCIe device IDs by substituting checks for SLI family information. This automatically picks up support on the newest hardware.
