    qtnfmac: assign each wiphy to its own virtual platform device · 616f5701
    Sergey Matyukevich authored
    Quantenna Pearl device exposes multiple (up to 3) radio interfaces under
    single PCIe function. So far all the wiphy devices were attached to the
    same pcie device. As a result, all different wireless network devices
    were reported under the same sysfs directory for pcie device, e.g.:
    
    $ ls  /sys/class/net/wlan0/device/net/
      wlan0 wlan1
    
    It turns out that such behavior may confuse various users of wireless
    subsystem. For instance, it turned out to be the case for:
    - Linux init systems, e.g. for renaming based on parent device
    - OpenWRT configuration scripts
    
    Suggested solution is to add an intermediate virtual platform device
    for each radio interface.
