> IB devices may invoke IB events that need a special treatment
> from the ib_client. For example, fatal event notification raised
> to registered clients due to an invalid port/device state after EEH.
> IB clients should be aware of this fatal event and not post any WR's
> to the device. Draining the QP, for example, is forbidden and will
> stuck forever waiting for the flushed work completions.

Where can we find a documentation to what should and should not
work in this event?
