4addr explanation

[Nikodem Ciesielski]

Hello

The question is:
Does 4addr mode require that wireless device to support WDS mode?

I'm trying to achive the following:
- bridge wire and wireless interface (Broadcom BCM43224) on Dell Latitude E6510
  os: Ubuntu 11.10 with  iw 3.3 (compiled and installed)
- setting wireless interface to 4addr mode and managed mode
- connect to Asus RT-n16 (firmware: TomatoUSB by shibby 1.28.0000 MIPSR2-085V K26 USB AIO)
*- * setting router to AP+WDS mode and add Laptop wireless MAC to WDS device

Simply I want to bridge wireless and wire intterface to work like an ordinary (wire) ethernet bridge.
And I can't. I followed the instrucion from:
http://nullroute.eu.org/~grawity/not-a-blog.html
topic: VirtualBox bridged network and WLAN

I think that my router refuse 4addr packages but I'm not sure.
Broadcom BCM43224 does not support WDS mode,
however it seems that 4addr mode can be set
and the wirelass card is able to assing with the router.
What can I do?

Best regards
Nikodem Ciesielski

mac80211 4addr mode is incompatible with the Broadcom specific WDS mode
implemented in your router.
