VintageNetBridge adds support for creating Ethernet bridges with VintageNet. Bridging two networks joins them together so that they form one LAN. One use case would be to join a WiFi mesh network with a wired Ethernet LAN. Devices on the mesh network would look like they're on the Ethernet LAN when in reality all traffic was being transferred through the bridge. For example, a DHCP server running on the Ethernet LAN would provide IP addresses for the WiFi mesh devices. While bridging is not always an appropriate way of joining networks, in this case, it enables one to provision multiple Mesh WiFi to Ethernet LAN devices for redundancy in the mesh while still looking like a normal IPv4 LAN.

To use, add :vintage_net_bridge to your mix dependencies like this:

def deps do
  [
    {:vintage_net_bridge, "~> 0.10.0"}
  ]
end

Bridges typically have names like "br0", "br1", etc. Here is an example configuration:

config :vintage_net,
  regulatory_domain: "US",
  config: [
    {"eth0",
     %{
       type: VintageNetEthernet,
       ipv4: %{method: :disabled}
     }},
    {"br0",
     %{
       type: VintageNetBridge,
       ipv4: %{method: :dhcp},
       vintage_net_bridge: %{
         interfaces: ["eth0", "mesh0"]
       }
     }},
    {"mesh0",
     %{
       type: VintageNetWiFi,
       ipv4: %{method: :disabled},
       vintage_net_wifi: %{
         user_mpm: 1,
         root_interface: "wlan0",
         networks: [
           %{
             key_mgmt: :none,
             ssid: "my-mesh",
             frequency: 2432,
             mode: :mesh
           }
         ]
       }
     }}
  ]
