The dispatcher scripts get called (since at least May 2011) with the 'IP
interface' of the device, because that's what is almost always useful
for IP and routing operations:
/* Backwards compat: 'iface' is set in this order:
* 1) VPN interface name
* 2) Device IP interface name
* 3) Device interface anme
*/
if (vpn_ip_iface)
*out_iface = g_strdup (vpn_ip_iface);
else if (ip_iface)
*out_iface = g_strdup (ip_iface);
else
*out_iface = g_strdup (iface);
in your case, the modem's control interface (and thus the NM Device
name) is cdc-wdm0 but the actual interface that IP will run on is
wwp0s29f7u2i4. Does that make sense?
If you're able to get logs from NM 0.9.x showing this isn't the case
there, I'd love to see them to figure out why they're doing that.
