Hi Bernd,
Sorry for the delay. I'll start looking at this patch, but I first need to play with
it a bit first and get more familiar with that area of the code.
In the mean time, I looked for your name in the copyright assignment list, and don't find
it. I think this patch is large enough to warrant one Do you already have one in place?
If not, please follow instructions here:
