Ethernet link state broken #105

With the milkv-duos-sd-v1.1.1-2024-0528.img the Ethernet link State on the Milk-DUO-S is detected the wrong way around. Without a cable attached the LEDs lit up and the network interface says

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether a2:0b:5d:3b:89:ff brd ff:ff:ff:ff:ff:ff
    inet 169.254.129.156/16 brd 169.254.255.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever

When attaching a cable the LED turn off and the interface says:

2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000
    link/ether a2:0b:5d:3b:89:ff brd ff:ff:ff:ff:ff:ff

I guess the driver for the Ethernet needs some love.

Okay - some failure here - that we didnt get a link on cable connect was a cabling issue. Still we continously see a link even if there is no cable connected.
