We do. See drivers/net/usb/cdc_mbim.c. It's a usbnet minidriver based on
reusing parts of cdc_ncm. It should be fairly complete, but the IP
session multiplexing and Device Service Streams features are not tested
on actual devices. I just haven't found any device with those features
yet. Any hints are appreciated...
The management protocol implementation is completely delegated to
userspace. The driver isn't involved at all. One implementation is
libmbim, which just had its 1.0.0 release:
http://www.freedesktop.org/software/libmbim/
The next ModemManager release will support MBIM devices using this
library.

Thanks for that pointer. I haven't seen the errata before. Will study
it, but fortunately we are protected against anything involving
management protocol updates.

Well, a "git grep MBIM drivers/" would be enough. But I'm happy to
answer your questions :)
