I have a dream, mesh11sd as a default package in GL-iNet routers

Routers

So what is mesh11sd:
mesh11sd is an uci command line dynamic parameter configuration daemon for 802.11s mesh networks.
It enables easy and automated mesh network operation with multiple mesh nodes.

it has options like mesh11sd connect which lists mesh11sd enabled nodes that can be connected, as it has no front end, GL's graphical user interface could parse this information for GL mac addresses and only allow GL devices to connect, so you could create a mesh11sd bridge between two Mangos, two Opals, two Velicas, or even different GL devices.
After connecting over the mesh11sd layer 2 bridge, the GL gateway node could query the GL mesh node for firmware version and model, and then list what wireless capabilities are available.

Thanks for your advice.

Sorry. There is no mesh feature in the PM team development plan.
If it has Luci UI, you can use it in the Luci interface at present.
But I will collect this first.
