Why do you add this modem to the whitelist?
I believe the clue is the

to set FLAG_WWAN instead of the default FLAG_ETHER | FLAG_POINTTOPOINT
Bjørn is right that this is the reason. The Fibocom MA510 and L610 are
cellular modems, so they require to be labelled as WWAN devices. As such
they require to be set up (using AT commands or similar) before the
connection can be used. Furthermore, WWAN devices get a different
routing metric assigned by the network manager than regular Ethernet
devices.
The net interface has the correct cdc_ether attributes so the
cdc_ether driver should bind automagically without any need for the
modem to be in the whitelist.
Yes, this sort of works against the class driver philosophy. But we've
already started down that road, so...
