[LEDE-DEV] * Add support of using device symlinks in network config. For example, it useful when using multiple usb devices that should be bound to certain usb ports. * Add uqmi 'sync' command call to release staled cid when preparing to setup new connection. As a result it prevents 'POLICY MISMATCH' errors.
