RE: [openib-general] [PATCH v2 1/7] AMSO1100 Low Level Driver.

Now that I've looked more into this, I'm not sure there's a
simple way for the IWCM to copy the pdata on the upcall.
Currently, the IWCM's event upcall, cm_event_handler(),
simply queues the work for processing on a workqueue thread.
So there's no per-event logic at all there.
Lemme think on this more.  Stay tuned.

Either way, the amso driver has a memory leak...

Having the IWCM copy the pdata during the upcall also leaves
the greatest flexibility for the driver on how/where the pdata
is captured. The IWCM has to deal with user-mode, indefinite
delays waiting for a response and user-mode processes that die
while holding a connection request. So it makes sense for that
layer to do the allocating and copying.

I've already coded and test this.  The IWCM will copy the pdata...
