Call ifconfig for 10.x.x.x with an appropriate netmask
If ifconfig is used with a 10.x.x.x ip address without specifying a netmask it assumes a class-a network and sets up a 10.x.x.x/8 route. We only need /24 here so the /24-netmask is needed.
Issue was noticed on an android9 device, thats why this MR is set to branch xenial_-_android9. It might be useful in branch "xenial" as well.
