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. 2022-04-16 16:25:28 +00:00			`#!/bin/sh`
