Subject: [PATCH 4/6] nss_dp_main: call unregister_netdev first in dp_remove
|
|
and carrifer_off
|
|
|
|
In dp_remove move unregister_netdev up before calling exit and deinit
|
|
and first call netif_carrier_off to stop any traffic from happening and
|
|
prevent kernel panics for napi in the middle of transfer.
