rogerpueyo: Sorry, I have no clue. I haven't experienced such behaviour with the MikroTik LHG 2, and the patch on GitHub will only affect this device. |

Hi,
Given the way the wired network is setup in the MikroTik LHG HB platform DTS file (qca9533_mikrotik_routerboard-lhg-hb):
ð1 { gmac-config { device = <&gmac>; }; };the link speed for the MikroTik LHG 2 is not properly reported at eth0. Instead, it appears as fixed at 1000 Mbps, while swconfig reports the actual speed for port #1:

Using the following network setup, which is also found in other devices (e.g., MikroTik SXT Lite 5):
ð0 {
status = "okay";
};
ð1 {
status = "okay";
};
eth0 reports the actual link speed:
