I've committed your diff - very nice to be able to dhclient cdce0 (and
route add default -ifp cdce0 if it doesn't pick up a route automatically)
rather than mess around making a ppp session to the phone. Now I'm
wondering how far to go with the manpage.

It probably makes sense to at least add something like this in caveats,

It would be handy to list the necessary commands somewhere in the
manual where people can find them easily offline, but I'm not sure
which section would be appropriate for that, maybe at the bottom
of description?

Hi!

The diff below makes cdce(4) to recognize cdce part of my Dell 5540 mini-pcie
card.

cdce port must be enabled before use by sending following to one
of the serial ports(should it be somehow documented in the manpage?):

AT+CFUN=1 # enable radio
AT+CGDCONT=1,IP,internet # configure apn
AT*ENAP=1,1 # enable cdce port
