[SCSI] iscsi class, iscsi_tcp, iser, qla4xxx: add netdevname sysfs attr
iSCSI must support software iscsi (iscsi_tcp, iser), hardware iscsi (qla4xxx), and partial offload (broadcom). To be able to allow each stack or driver or port (virtual or physical) to be able to log into the same target portal we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and the target tuple [TARGETNAME, CONN_ADDRESS, CONN_PORT] to id a session. This patch adds the netdev name, which is used by software iscsi when it binds a session to a netdevice using the SO_BINDTODEVICE sock opt. It cannot use HWADDRESS because if someone did vlans then the same netdevice will have the same mac and the initiator,target id will not be unique.
