wpa_supplicant doesn't manage network interfaces. I assume you're using ConnMan
for this? If so, ConnMan sets the IFF_DYNAMIC flag. See

iwd doesn't use IFF_DYNAMIC in its DHCP implementation at the moment.

According to 'man netdevice':

IFF_DYNAMIC The addresses are lost when the interface
goes down.

I doubt this is the cause of your DHCP / connection problems.
