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.
