cat /etc/udev/rules.d/70-persistent-net.rules
-
SUBSYSTEM=="net"- This tells Udev to ignore devices that are not network cards. -
ACTION=="add"- This tells Udev to ignore this rule for a uevent that isn't an add ("remove" and "change" uevents also happen, but don't need to rename network interfaces). -
DRIVERS=="?*"- This exists so that Udev will ignore VLAN or bridge sub-interfaces (because these sub-interfaces do not have drivers). These sub-interfaces are skipped because the name that would be assigned would collide with their parent devices. -
ATTR{address}- The value of this key is the NIC's MAC address. -
ATTR{type}=="1"- This ensures the rule only matches the primary interface in the case of certain wireless drivers, which create multiple virtual interfaces. The secondary interfaces are skipped for the same reason that VLAN and bridge sub-interfaces are skipped: there would be a name collision otherwise. -
KERNEL=="eth*"- This key was added to the Udev rule generator to handle machines that have multiple network interfaces, all with the same MAC address (the PS3 is one such machine). If the independent interfaces have different basenames, this key will allow Udev to tell them apart. This is generally not necessary for most Linux From Scratch users, but does not hurt. -
NAME- The value of this key is the name that Udev will assign to this interface.
