Resolve network devices by first trying 'network_get_device' (L3) and falling back to 'network_get_physdev' (L2) on failure, which allows using Wireguard interfaces. Both are needed to avoid breaking existing usage for some interfaces (e.g. 'wan'). Also add myself as a maintainer. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
