55-down-interfaces.sh suspend script reads in incorrect wireless interface name.

[Tomas Cassidy]

The ACPI script /etc/acpi/suspend.d/55-down-interfaces.sh seems to be run when the computer is going into suspend mode and shuts down all network interfaces. These network interfaces are obtained from the output of the 'ifconfig' command. On my laptop, the output of 'ifconfig' gives the wireless interface name as "wlan0_ren" when the correct interface name is actually "wlan0_rename" (given by iwconfig, and ubuntu default name). This prevents the script from shutting down the wireless network interface when going into suspend mode, and therefore prevents it from being started again when coming out of suspend (the resume script seems to use the same interface names as the suspend script). I thought about changing the interface name for the wireless interface since ifconfig might have a name-size limit, but I have no idea how I should be doing this.
