Replicant

In hardware/replicant/wlan/wifi_hal/wifi_hal.cpp we have:
_wifi_interface(const char *name)
{
    if (strncmp(name, "wlan", 4) != 0 && strncmp(name, "swlan", 5) != 0 && strncmp(name, "p2p", 3) != 0) {
        /* not a wifi interface; ignore it */
        return false;
    } else {
        return true;
    }
}

It might be a good idea to check if devices are renamed sometimes and if they are to find a better way to detect if an interface is a WiFi interface.
