13.4.1.3 Conguring an Undetected Network Card
Your card may not be detected correctly. In this case, the card is not included in the list
of detected cards. If you are sure that your system includes a driver for your card, you
can congure it manually. You can also congure special network device types, such
as bridge, bond, TUN or TAP. To congure an undetected network card (or a special
device) proceed as follows:
1
In the Network Devices > Network Settings > Overview dialog in YaST click Add.
2
In the Hardware dialog, set the Device Type of the interface from the available options
and Conguration Name. If the network card is a PCMCIA or USB device, activate
the respective check box and exit this dialog with Next. Otherwise, you can dene
the kernel Module Name to be used for the card and its Options, if necessary.
In Ethtool Options, you can set ethtool options used by ifup for the interface.
See the ethtool manual page for available options. If the option string starts with
a - (for example -K interface_name rx on), the second word in the string
is replaced with the current interface name. Otherwise (for example autoneg off
speed 10) ifup prepends -s interface_name.
