Sukadev, my apologies. This patch does need some changes,

I was wrong. This should be fixed right now. I _think_ this is easy,
and I was going to finish this patch yesterday, but - sorry! - I just
can't switch to "kernel mode" these days, I am fighting with some urgent
tasks on my paid job.

Please feel free to solve this issue yourself if you wish. As for me, I'm
forgetting about the kernel until at least the next weekend.

Also, Pavel has some ideas how to do this all on receiver's path, perhaps
this makes more sense (not that I completely agree, but I didn't see the
code yet).

Sorry for inconvenience,

Oleg.
