Subject: [PATCH] [PATCH v5 1/3] ISCSISTART: Saved ibft boot info to the
 session

Patch and description from Eddie Wai:

Three new session sysfs parameters are introduced:
boot_root   - holds the ibft boot root folder name
boot_nic    - holds the ibft boot ethernetN name
boot_target - holds the ibft boot targetN name

This patch copies over the /sys/firmware/<boot_root>/ethernetN/targetN
info
from the boot context to the node_rec.
