So the netdev_info() call works\non a partially uninitialized netdev.\n\nFix this by calling igc_ptp_init() after register_netdev(), right\nafter the media autosense check, just as in igb. Add a comment,\njust as in igb.\n\nNow the log message is fine:\n\n[ 5.200987] igc 0000:01:00.0 eth0: PHC added"}, {"lang": "es", "value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: igc: corrige una entrada de registro usando netdev no inicializado. Durante la prueba exitosa, igc registra esto: [5.133667] igc 0000:01:00.0 (net_device sin nombre) (sin inicializar): PHC agregado ^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ La raz\u00f3n es que igc_ptp_init() se llama muy temprano, incluso antes de Register_netdev( ) ha sido llamado. Entonces la llamada netdev_info() funciona en un netdev parcialmente no inicializado. Solucione este problema llamando a igc_ptp_init() despu\u00e9s de Register_netdev(), justo despu\u00e9s de la verificaci\u00f3n de detecci\u00f3n autom\u00e1tica de medios, tal como en igb.
