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.
