Hi, I'm seeing some odd behaviour with the netdev trigger and some WiFi interfaces.
When the WiFi interface has never been brought up (so is in an operationally disabled state), if I bind a LED to the netdev trigger, setting the device_name to the WiFi interface name and enable the "link" property, the LED illuminates, indicating that the WiFi device has link - but it's disabled. If I up/down the WiFi interface, thereby returning it to the original state, the link LED goes out. I suspect ledtrig-netdev.c needs to check that the device is both up (dev->flags & IFF_UP) and netif_carrier_ok(dev) both return true, rather than just relying on netif_carrier_ok(). I don't think using netif_running() is appropriate, as that will return true before ndo_open() has been called to initialise the carrier state. Agreed? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
