22.6. Adding a Network Device
The process of adding a network device has changed with the migration of the 2.4 kernel to the 2.6 kernel:
The proc file system is no longer used to control or obtain status on network devices.
The new sys file system now provides facilities for controlling devices.
/sys/class/net/interface_name/device now provides status on active devices.
interface_name is a name such as eth0 or eth2 that is given to a network interface by the device driver when the device is configured.
/etc/chandev.conf no longer exists.
The sys file system now contains the information that was placed in /etc/chandev.conf.
/etc/modules.conf no longer exists.
Network interface alias specifications are now placed in /etc/modprobe.conf.
Section 22.6.1, “Adding a qeth Device” describes in detail how to add a qeth device to an existing instance of Red Hat Enterprise Linux. Section 22.6.2, “Quick Reference for Adding Network Devices” is a quick reference for installing other IBM System z network interfaces.
