Setup:
HW:
Fanstel-WT02C40C (nrf5340/7002)
WIZ5500 ethernet
Versions tested:
ncs-v2.6.0
ncs-v2.5.2
ncs-v2.4.2
Issue:
When attempting to integrate Ethernet and BLE I'm running into an issue where DHCP fails to start the iface on the versions listed above, when introducing CONFIG_BT=y into my system.
I have a working implementation for both my BLE Mesh and for Ethernet, which failed when integrating together so I decided to start piecemeal it together slowly, and on the first step of adding CONFIG_BT=y to my project, is when DHCP begins failing to start Ethernet.

Code:
struct net_if *iface;
iface = net_if_get_default();
if (iface == NULL) {
printk("Error getting default network interface.\n");
return;
}
// Link status callback handler
net_mgmt_init_event_callback(&cb, net_mgmt_handler, NET_EVENT_ETHERNET_CARRIER_ON | NET_EVENT_ETHERNET_CARRIER_OFF);
net_mgmt_add_event_callback(&cb);
// Start DHCP
net_dhcpv4_start(iface);I also need to add WiFi to it, but that's another bridge to be crossed after dealing with this.
