Subject: [PATCH] Correction XDP file path, wwan_loop service and add hotplug
 iface wwan script

XDP file path was in the var folder which is a virtual link to tmp folder.

add hotplug script to put the script xdp on the interface wwan when the command ifup -a wwan0 is called.

wwan_loop service crash on the launch, because it launched before the interface wwan set up.
