Description (partial)

Symptom:
1. CWMP triggers DHCP discovery and delays process by 12 seconds on every run
2. The DHCP discovery is sent with unexpected values:
 - using default vendor class-id (ciscopnp) even though one is configured under the interface;
 - class-id "CWMP";
 - "Client MAC address field" is populated with MAC address of the first interface of the router (although L2 src MAC is correct for the interface).
3. "Temp IP addr: 0.0.0.0 " may be seen for a short period of time under the "show dhcp lease"

Conditions:
CWMP+DHCP configured on the device.
