+devif_num of -1 indicates you don't care what device interface number is chosen, omitting it indicates this is a range of devices for which you want to force to be detected as a particular type, qeth devices can't be forced as a range as it makes no sense for them.
+The data_devno field is only valid for qeth devices, all parameters including & after memory_usage_in_k can be set optionally, if not set they
 go to default values. memory_usage_in_k ( 0 the default ) means let the driver choose,checksum_received_ip_pkts & use_hw_stats are set to false

 .It
 Tells the channel layer to force ctc0 if detected to use cuu's 7c00 & 7c01 port,port_no is the relative adapter no on lcs, on ctc/escon this field is the ctc/escon protocol number ( default 0 ), don't do checksumming on received ip packets & as ctc doesn't have hardware stats so it ignores this parameter. This can be used for instance to force a device if it presents bad sense data to the IO layer & thus autodetection fails.
