The first two patches are small fixes for issues that were spotted during the original code testing. The 3rd patch completes my suggestion to make the parent device attribute (IFLA_PARENT_DEV_NAME) generic by revealing the netdev parent device to userspace using this attribute. The 4th patch was added to make it easier to test iproute2 changes, in fact it just copies the definitions from the kernel headers to iproute2. Finally, 5th and 6th patches provide an example of userspace support for WWAN links management. At the moment I do not have access to any WWAN hardware, so the code was only lightly tested at runtime. 1. https://lore.kernel.org/netdev/20210602082840.85828-1-johannes@sipsolutions.net
