Module Parameters
Optional parameters for the driver can be supplied as command line
arguments to the insmod command. Typically, these parameters are set in
the file /etc/modules.conf (see the man page for modules.conf). These
parameters take the following form:
=value[,value,...]
where the multiple values for the same parameter are for multiple Allied
Telesis Gigabit Ethernet Network adapters installed in the system.
Note
The default or other meaningful values are used when invalid values
are selected. Some combinations of parameter values may conflict
and lead to failures. The driver cannot detect all such conflicting
combinations.
The module parameters are listed below:
 line_speed
Selects the line speed of the link. This parameter is used together
with full_duplex and auto_speed to select the speed and duplex
operation of the link and the setting of Auto-Negotiation. Choose
from the following selections:
– 0 - Autonegotiate for highest speed supported by link
partner (default)
– 10 - 10 Mbps
– 100 - 100 Mbps
– 1000 - 1000 Mbps
If line_speed is set to 10, 100, or 1000 and the auto_speed is set to
1, the NIC autonegotiates for the selected speed (and selected
duplex mode). If auto_speed is set to 0, the selected speed and
duplex mode are set without Auto-Negotiation. Note that 1000
Mbps must be negotiated for copper twisted pair links.
 auto_speed
Enables or disables Auto-Negotiation. Choose from the following
selections:
– 0 - Auto-Negotiation disabled
– 1 - Auto-Negotiation enabled (default)
