    [SCSI] iscsi class, iscsi_tcp, iser, qla4xxx: add netdevname sysfs attr · d8196ed2
    Mike Christie 提交于
    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.
