Hey guys,

Just got this bugreport in ModemManager:

This is a Sierra device which exposes a cdc-wdm MBIM port. The port
seems to send radio-state MBIM indications over and over again, but
won't reply to our MBIM open requests, so ModemManager ends up
deciding it is not MBIM. Has anyone seen something like this before?
