Hi list, I'm very new to this list, but we have the task to realize a linux based bridging device with fast loop detection support. We want to built an embedded linux device ( arm7 or arm9 based) with 3 ethernet interfaces. As I understood, the linux bridging code contains already stp (802.1d) support. So we could try to use this and to play with the stp timing constants, but I think, it would be much better to implement the 802.1w extensions in the bridging code. Are there any hints re- garding this subject and is there any detailed documentation about the linux bridging code (besides the source code itself) or is there already a project running to implement 802.1w for a recent linux kernel? thanks a lot and best regards Christian Schroeder Dr.-Ing.
