  "message": "ncm: fix carrier lost on link-state notify collision\n\ntud_network_link_state() delivered the NETWORK_CONNECTION notification\nedge-triggered and fire-once: if a previous notification was still in\nflight, notification_xmit() returned early and the notification for the\nnew link state was never queued. Because link_is_up is committed before\nthe send, the host could be left reporting a stale carrier state - e.g.\na permanent NO-CARRIER after a link up. The notification state was also\nmutated from both the caller and the notify xfer-completion callback\nwith no serialisation, so on RTOS ports where tud_network_link_state()\nruns in a task other than tud_task() the two could race.\n\nDefer the whole link-state update onto the usbd task, so it can no\nlonger race the completion callback. A collision with an in-flight\nnotification is resolved by re-arming notification_xmit_state and\nletting the existing completion callback drive it forward on the next\nxfer completion, rather than adding a separate pending/retry flag.\n\nA link toggle does not change the link speed, so strictly only the\nNETWORK_CONNECTION notification needs (re)sending, but reusing the\nexisting speed-then-connection state machine keeps the fix on a single,\nalready-serialised code path.\n\nCloses #3760\n",
