Introduction
This document describes the requirements of software components including
driver and wpa_supplicant for Realtek mesh function which is compatible with IEEE
802.11s standard; also provides examples to setup mesh network using
wpa_supplicant.
2.

Software Requirements
Below are the requirements of each software components which are needed to
enable Realtek mesh function:
Software Component

Requirement

Kernel

ver. >= 3.11, with CFG80211

Driver

ver. >= 5.3, with CFG80211

wpa_supplicant

wpa_supplicant_8_O_8.x_rtw_r26058 or later

2.1. Driver Configurations
l CONFIG_RTW_MESH
l CONFIG_IOCTL_CFG80211
To enable driver’s mesh function, these two shall be defined before
compilation.
2.2. Wpa_supplicant Configurations
l CONFIG_MESH=y
To enable wpa_supplicant’s mesh function, adding this configuration to
wpa_supplicant/wpa_supplicant/.config before compilation.
3.

Setup Mesh using wpa_supplicant
Mesh is setup using wpa_supplicant with mesh specific global field
configurations and mesh network profile in runtime wpa_suppliant configuration file.
l

Global Field Configurations

Configuration

Descriptions

user_mpm

0: MPM handled by driver
1: MPM handled by wpa_supplicant
Shall be 1 for Realtek mesh

max_peer_links

Maximum number of mesh peering allowed.
Maximum is 8 for Realtek mesh.

mesh_max_inactivity

Timeout in seconds to detect STA inactivity

l

Network Field Configurations

Configuration

Descriptions

ssid

Mesh ID for this mesh network

Mode

5: Mesh

frequency

Operating frequency for this mesh network

key_mgmt

NONE: For open mesh network
SAE: For secured mesh network

Below is for secured mesh
psk

PSK used by secured mesh network

3.1. Open Mesh Setup
Below is a sample runtime wpa_supplicant configuration file for an open mesh
network profile:
ctrl_interface=/var/run/wpa_supplicant
user_mpm=1
max_peer_links=8
mesh_max_inactivity=20

network={
ssid="open_mesh"
mode=5
frequency=2432
key_mgmt=NONE
}

Execute the mesh function enabled wpa_supplicant with the above configuration
file (ex: open_mesh.conf) on Realtek WLAN interface (ex: wlan0) in background:
root@rtkpc #./wpa_supplicant –Dnl80211 -iwlan0 -c./open_mesh.conf -B

3.2. Secured Mesh Setup
Below is a sample runtime wpa_supplicant configuration file for a secured mesh
network profile:

ctrl_interface=/var/run/wpa_supplicant
user_mpm=1
max_peer_links=8
mesh_max_inactivity=20

network={
ssid="secured_mesh"
mode=5
frequency=2432
key_mgmt=SAE
psk="password"
}

Execute the mesh function enabled wpa_supplicant with the above configuration
file (ex: secured_mesh.conf) on Realtek WLAN interface (ex: wlan0) in background:
root@rtkpc #./wpa_supplicant –Dnl80211 -iwlan0 -c./secured_mesh.conf -B

※ Multiple mesh network profiles and even profiles of other mode (ex:
Infrastructure or ad-hoc mode) can exist in the same configuration file and then
switched by “select_network” command.
