这是我的 wifi 设备的带有iw phy命令的属性。
我需要使用此 WiFi 适配器进行网状配置。
这是 ralink rt3070 USB 设备。
另外，在nano pi中安装了ubutnu操作系统。

root@181RX:/home/pi# iw dev $w interface add mesh0 type mp

命令失败：不支持操作（-95）

我的设备不支持mesh？

Answer 1

不，您的设备不支持 802.11s MESH。否则你的iw list输出将类似于：

Supported interface modes:
  * IBSS
  * managed
  * AP
  * AP/VLAN
  * monitor
  * mesh point

笔记网格点在底部。

Answer 2

我通过内核配置启用了 mac80211 网格。
