When connecting my Linux computer (Ubuntu 22.04, Kernel 5.15) to the network I see an ARP Announcement according to the Wireshark print screen below.

For an embedded device I build my Linux using yocto (dunfell) with Kernel 5.10. When I connecting this device to the network I doesn't see the ARP Announcement.

Where do I have to enable this ARP Announcement in the yocto recipe, are additional packages required for this? Or is it a Linux kernel configuration? The embedded device has support for ARP it self and returns correctly to requests, it just doesn't send the optional Announcement after the interface setup.

Note: I originally asked this question on SO and got the hint that this forum would be the better palace to ask.
