I have to weigh in on the side of SW here - there's already logic to
handle other events in SW, so supporting client reregister in SW is
trivial.  Further, the Windows stack handles this in SW, and I don't
see any reason why that should change since it's already in place and
working.  It would be nice to have some similarities between the
stacks, especially for cases where the FW would affect the behavior of
the HCA.  We don't want a FW for Linux and a different one for
Windows.
