F.6. Adding a Network Device
The process of adding a network device has changed greatly for Red Hat Enterprise Linux. This is due in part to 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 ctc2 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 F.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 F.6.2, “Quick Reference for Adding Network Devices” is a quick reference for installing other zSeries network interfaces.
