Description of problem:
Not sure if this is a bug per se, but can we clarify if this is the expected behaviour and perhaps have it documented?

1. 1. 1. Creating interfaces:
         [root@storageqe-87 ~]# iscsiadm -m iface -o new -I iface0
         New interface iface0 added
         [root@storageqe-87 ~]# iscsiadm -m iface -o new -I iface1
         New interface iface1 added

1. 1. 1. Assigning them a mac address - please note the could not scan message:
         [root@storageqe-87 ~]# iscsiadm -m iface -I iface0 -o update -n iface.hwaddress -v b4:96:91:a0:68:8a
         iscsiadm: Could not scan /sys/class/iscsi_transport.
         iface0 updated.
         [root@storageqe-87 ~]# iscsiadm -m iface -I iface1 -o update -n iface.hwaddress -v b4:96:91:a0:68:8b
         iface1 updated.

1. 1. 1. Discovering a target using the new ifaces
         [root@storageqe-87 ~]# iscsiadm -m discovery -t st -p 172.16.0.10 -I iface0
         172.16.0.10:3260,0 iqn.2002-03.com.compellent:5000d31005728037
         172.16.0.10:3260,0 iqn.2002-03.com.compellent:5000d31005728042
         [root@storageqe-87 ~]# iscsiadm -m discovery -t st -p 172.16.1.10 -I iface1
         172.16.1.10:3260,0 iqn.2002-03.com.compellent:5000d31005728041
         172.16.1.10:3260,0 iqn.2002-03.com.compellent:5000d31005728044

1. 1. 1. Two ifaces after discovery
         [root@storageqe-87 ~]# iscsiadm -m iface
         iface0 tcp,b4:96:91:a0:68:8a,<empty>,<empty>,<empty>
         iface1 tcp,b4:96:91:a0:68:8b,<empty>,<empty>,<empty>
         default tcp,<empty>,<empty>,<empty>,<empty>
         iser iser,<empty>,<empty>,<empty>,<empty>

1. 1. 1. Logging into the target
         [root@storageqe-87 ~]# iscsiadm -m node -l
         Logging in to [iface: iface0, target: iqn.2002-03.com.compellent:5000d31005728037, portal: 172.16.0.10,3260]
         Logging in to [iface: iface0, target: iqn.2002-03.com.compellent:5000d31005728042, portal: 172.16.0.10,3260]
         Logging in to [iface: iface1, target: iqn.2002-03.com.compellent:5000d31005728041, portal: 172.16.1.10,3260]
         Logging in to [iface: iface1, target: iqn.2002-03.com.compellent:5000d31005728044, portal: 172.16.1.10,3260]
         Login to [iface: iface0, target: iqn.2002-03.com.compellent:5000d31005728037, portal: 172.16.0.10,3260] successful.
         Login to [iface: iface0, target: iqn.2002-03.com.compellent:5000d31005728042, portal: 172.16.0.10,3260] successful.
         Login to [iface: iface1, target: iqn.2002-03.com.compellent:5000d31005728041, portal: 172.16.1.10,3260] successful.

1. 1. 1. Two new interfaces appeared:
         [root@storageqe-87 ~]# iscsiadm -m iface
         iface0 tcp,b4:96:91:a0:68:8a,<empty>,<empty>,<empty>
         iface1 tcp,b4:96:91:a0:68:8b,<empty>,<empty>,<empty>
         tcp.b4:96:91:a0:68:8a tcp,b4:96:91:a0:68:8a,172.16.0.87,default,<empty>
         tcp.b4:96:91:a0:68:8b tcp,b4:96:91:a0:68:8b,172.16.1.87,default,<empty>
         default tcp,<empty>,<empty>,<empty>,<empty>
         iser iser,<empty>,<empty>,<empty>,<empty>

(Even if I assign iface0 and iface1 IP beforehand, the new ifaces are still being created)
