+## Script to set a mac address to a ethernet device.
+## The device takes the following parameter from /proc/cmdline:
+## - setmac.set_mac_addr=xx:xx:xx:xx:xx   -> the MAC address to set
+## - setmac.set_iface=			-> the interface name to which the MAC should get set
+## - setmac.set_module=			-> module driver name 
+##
+## The setmac.set_mac_addr= parameter is mandatory! while
+## either setmac.set_iface or setmac.set_module need to be set.
+##
+## If setmac.set_iface is given the MAC is set to the device,
+## but only if the device has a random MAC address in sysfs.
+##
+## If setmac.set_module is set the first device/interface with a 
+## random MAC address gets the given MAC assigned (marked in sysfs).
