LIN8-4329 : System doesn't get dhcp IP address

Severity: Standard
Applicable for: Wind River Linux 8
Component/s: unknown


On Arm Beaglebone and Intel x86-64 Baytrail, when system boots up, there is no dhcp IP address assigned.

dhclient.service doesn't exist. 
systemd-networkd.service is in failed state (it's active for about 1min before goes into failed state)

On Beaglebone (at least), this will cause the system reboot most of the time.


Specify "ip=dhcp" in kernel commandline will get a IP for the target.

Steps to Reproduce

- build and deploy an image on Beaglebone or Baytrail
- boot the system
- ifconfig no IP assigned.
root@WR-LX-813E:~# ifconfig
lo        Link encap:Local Loopback  
          inet addr:  Mask:
