Build error in Sample App for OpenThread NCP

[vijayrao1988]

Describe the bug
When attempting to build the OpenThread NCP sample app for Silicon Labs Thunderboard Sense board.
Building and flashing other sample apps like blinky and hello-world work fine. The build error refers to CONFIG_NET_CONFIG_IEEE802154_DEV_NAME being undeclared. Is this supposed to supplied as a build argument?

To Reproduce
Steps to reproduce the behavior:
Command:
west build -p -b efr32mg_sltb004a samples/net/openthread/ncp

Exits with the following error:
/home/blitz/zephyrproject/zephyr/subsys/net/lib/openthread/platform/radio.c:185:33: error: 'CONFIG_NET_CONFIG_IEEE802154_DEV_NAME' undeclared (first use in this function)
185 | radio_dev = device_get_binding(CONFIG_NET_CONFIG_IEEE802154_DEV_NAME);

FATAL ERROR: command exited with status 1: /usr/bin/cmake --build /home/blitz/zephyrproject/zephyr/build

Expected behavior
A sample build of the OpenThread NCP would demonstrate capability of Zephyr running simple communications over the Thread stack.

Impact
As I am unable to run this quick check before we move out from Silabs stack, it is stopping me from convincing my team to move to Zephyr as our long term dev platform for our OpenThread based IoT devices.

@vijayrao1988 I am not sure 802.15.4 is supported on Silicon Labs devices due to the requirement for a binary module. @mnkp can I'm sure expand on that a bit.

[carlescufi]

The build error refers to CONFIG_NET_CONFIG_IEEE802154_DEV_NAME being undeclared. Is this supposed to supplied as a build argument?

No, this is a Kconfig option. Looking at the list of supported drivers I don't see anything related to Silicon Labs. Likely because of this issue

[carlescufi]

Closing since this is not supported on SiLabs boards. Please follow this issue to get updates on the binary blob discussion.
