The target file is drivers/net/ethernet/via/via-rhine, which is used to build via-rhine.ko. I hope you can help me check my findings: [1] In the normal process, netif_napi_add is called in rhine_init_one_common, but netif_napi_del is not called in rhine_remove_one_pci. However, many other ethernet card drivers call them in pairs, even in the error handling paths, such as r8169 and igb. [2] In my running test, if dma_mapping_error in alloc_rbufs is failed, system crash occurs when executing netif_receive_skb in rhine_napipoll, but I can not find the specific reason. Could you help me check these findings? Thank you very much, and I'm looking forward to your reply. -- Jia-Ju Bai -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
