Hi Johan,
I have addressed all you comments except one, please see bellow. I
will wait for the review on the subdrivers before submitting a new

You are right, but I think we need a reinit_completion(). Technically
we don't, as we don't use complete_all(), but I feel it is cleaner
that way. I will move the initialization in probe and add the
reinit_completion() in free_rx_slot. Is that OK with you?
