Here's a respin of the series to create netdevs through the WWAN framework. I haven't tested it at all, since I don't have any such hardware, so I guess there will be some bugs ... It'd be best if somebody else takes over here, Loic, maybe I can talk you into getting the generic bits done if you have a test case? :) This applies on top of the IOSM driver series posted here: https://lore.kernel.org/r/20210520140158.10132-1-m.chetan.kumar@xxxxxxxxx I've included the first bugfix patch only so it actually all can apply properly, not really needed for review. johannes
