Ethernet interface going down when connecting to WiFi in Client Mode on imx8mplus

Hi NXP,

[Description]

When we try connecting the board to a network via client mode using wlan0 interface, once we run udhcpc command, the ethernet interface goes down.

In ifconfig, we could only see wlan0 and lo interfaces.

Please find the set of commands used:

# ifconfig wlan0 up
# cd /etc
# wpa_passphrase “ESSID” “password” > wpa_supplicant.conf
# wpa_supplicant -B -D nl80211 -i wlan0 -c wpa_supplicant.conf
# udhcpc -i wlan0

[Expected]

We need eth0, eth1 and wlan0 to be UP at the same time as per our use case.

[NOTE] This issue is not observed in WiFi AP Mode.

Please find the complete dmesg logs for reference.
