From 9a99425f0736a416442525ac7b15903173888b86 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 25 Feb 2016 09:56:04 -0800 Subject: iscsi_ibft: Add prefix-len attr and display netmask The iBFT table only specifies a prefix length, not a netmask. And the netmask is pretty much pointless for IPv6. So introduce a new attribute 'prefix-len'. Some older user-space code might rely on the netmask attribute being present, so we should always display it.

On some adapters this includes a hardware iscsi initiator. The same adapters in a normal (no extra licenses) mode of operation can be used as a software iscsi initiator. In addition, software iscsi boot initiators are becoming a standard part of many vendors uefi implementations. This is creating difficulties during early boot/install determining the proper configuration method for these adapters when they are used as a boot device. The attached patch creates sysfs entries to expose information from the acpi header of the ibft table. This information allows for a method to easily determining if an ibft table was created by a ethernet card's firmware or the system uefi/bios. In the case of a hardware initiator this information in combination with the pci vendor and device id can be used to ascertain any vendor specific behaviors that need to be accommodated.
