    Subject[PATCH 4.14 13/57] net/ncsi: Use real net-device for response handler
    Date
    From: John Wang <wangzhiqiang.bj@bytedance.com>

    [ Upstream commit 427c940558560bff2583d07fc119a21094675982 ]

    When aggregating ncsi interfaces and dedicated interfaces to bond
    interfaces, the ncsi response handler will use the wrong net device to
    find ncsi_dev, so that the ncsi interface will not work properly.
    Here, we use the original net device to fix it.
