Implement support for modifying IPOIB CQ moderation params
This can be used to tune at run time the paramters controlling
the event (interrupt) generation rate and thus reduce the overhead
incurred by hadling interrupts resulting in better throughput.

As IPoIB uses one CQ per device, why you use the tx_ and rx_ prefixes in
the structure name (and later propagated into the documentation, mindset
of users etc etc). Its confusing, please change it to be
<coalesce_usecs, max_coalesced_frames>
Or.
