Hi Alexey

I reworked your patch a little. I renamed wake to callback, which is
more generic. You can do real work in DSRs, you just have to be
careful. So you don't always need to wake up a thread.

Since there is no test case for this new feature, it is possible i
have broken it. So please can you test it. If it all works i will then
commit it.

Do you think you could add a testcase to the can loop back driver
which uses this feature?

     Thanks
        Andrew
