get_device_mapping_from_network(initiator_list, target_list)

Get device mapping from FC network.

Gets a filtered list of initiator ports and target ports for each SAN available. :param initiator_list: list of initiator port WWN :param target_list: list of target port WWN :returns: device wwn map in following format

{
    <San name>: {
        'initiator_port_wwn_list':
        ('200000051E55A100', '200000051E55A121'..)
