    Make sure:

    • the kernel has loaded the drivers for your NIC
    • DHCP is enabled for IP autoconfiguration

    Then add ip=dhcp to the kernel command line and you're good to go.

  2. From KConfig

    CONFIG_IP_PNP:

    This enables automatic configuration of IP addresses of devices and of the routing table during kernel boot, based on either information supplied on the kernel command line or by BOOTP or RARP protocols.

    So it can't be used with plain DHCP For using with DHCP you need additional option.
