From 27d6ac0a6e830043bd5db89fee8adddb41ada2f7 Mon Sep 17 00:00:00 2001 From: James Smart Date: Thu, 22 Feb 2018 08:18:42 -0800 Subject: [PATCH] scsi: lpfc: Add SLI-4 if_type=6 support to the code base New hardware supports a SLI-4 interface, but with a new if_type variant of 6. If_type=6 has a different PCI BAR map, separate EQ/CQ doorbells, and some changes in doorbell formats. Add the changes for the if_type into headers, adapter initialization and control flows. Add new eq and cq handlers. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
