    It seems to help. The initial assignment looks good:
    +-01.1-[05-9b]----00.0-[06-27]--+-00.0-[07]----00.0 Intel
    Corporation DSL3510 Thunderbolt Port [Cactus Ridge]
    | +-03.0-[08-0f]--
    | +-04.0-[10-17]--
    | +-05.0-[18-1f]--
    | \-06.0-[20-27]--
    After hotplug it looks like this:
    +-01.1-[05-9b]----00.0-[06-29]--+-00.0-[07]----00.0 Intel
    Corporation DSL3510 Thunderbolt Port [Cactus Ridge]
    |
    +-03.0-[08-11]----00.0-[09-11]----00.0-[0a-11]----00.0 Broadcom
    Corporation NetXtreme BCM57762 Gigabit Ethernet PCIe
    | +-04.0-[10-17]--
    | +-05.0-[18-1f]--
    | \-06.0-[20-27]--
    (Note that the bridge numbers are not disjoint)

    dmesg is attached.

    What is the status of the patch? Will it be merged for 3.14?

    Cheers,
    Andreas
