| Subject: [PATCH] myri10ge: fix rmmod crash |
| |
| commit cda6587c21a887254c8ed4b58da8fcc4040ab557 upstream. |
| |
| Rmmod myri10ge crash at free_netdev() -> netif_napi_del(), because napi |
| structures are already deallocated. To fix call netif_napi_del() before |
| kfree() at myri10ge_free_slices(). |
