Do these devices work with the Icera AT commands that retrieve the
static IP addressing details?  I don't think it makes a ton of
difference whether we use static or DHCP on these devices, with the
possible exception of IPv6 support later on.  Ideally, we can autodetect
which devices want DHCP via AT commands or such.  Is that possible?
