Great! Thanks for picking that up.

AFAIK no.

Currently only IPv6 is supported natively (though we support IPv4 via the
lwIP pkg). But we don't say no if we get IPv4 support for GNRC ;-).

The CC3200 delivers a full embedded network stack right? If so, I would
rather suggest to either implement against GNRC's NETAPI [1] or the sock
API [2], rather than netdev. Though it is the CC3200 network device,
porting it to the netdev API might lead to problems that API rather thought
to be used for link-layer networking.

Kind Regards,
Martine
