Hi everybody!

I bisected the problem with the following result:

aa9421041128abb4d269ee1dc502ff65fb3b7d69 is the first bad commit
commit aa9421041128abb4d269ee1dc502ff65fb3b7d69

    net: init ingress queue

    The dev field of ingress queue is forgot to initialized, then NULL
    pointer dereference happens in qdisc_alloc().

    Move inits of tx queues to netif_alloc_netdev_queues().
