Trying to get at MT7688 (rt3050 ethernet driver) eth0 link up/down events. Right now only the kernel log (dmesg) seems to know when eth0 link go up or down. So all interfaces that depend on eth0 stay "connected" when eth0 goes down, the routing table continues to favor those interfaces, and of course I can't get a ethernet PHY LED to function if I don't know when the link has changed state. the operstate also does not change. uevent and udevadm show nothing when link state changes. My fist quesion is, is this a bug or am I missing something? If it is a bug, I am happy to fix it, who/what/when/where should the link state change notification come from and where should it be broadcast to?
