UINIT: netif_napi_del() ¦ ? ...... ¦ ? INIT: netif_napi_add() ¦ ? ...... global reset start ¦¦ ?? UP: napi_enable()(skip)...... ¦¦ ?? ...... napi_disable() In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.
