In an interrupt callback function, the paramter intr_handle which 
is registered at rte_intr_callback_register call is passed back.
It is supposed to feed rte_intr_enable, but it is not gareenteed 
to contain paramters as required, since it is a copy of 
rte_ethdev->intr_handle, if some field need to be updated (like max_intr)
driver need to unregister and register the callback function again.
So is it necessary to pass back a copy of intr_handle? why don't 
use rte_ethdev->intr_handle directly to feed rte_intr_enable?
if look at the prototpye of rte_intr_callback_fn, void* cb_arg 
can be used to pass anything by the driver and the typical way 
is to pass a rte_ethdev(or any embedded bus dev) instance 
(actually, almost all driver implemented this already), and use 
this instance to get the right intr_handle.

One of the patch clean up this and the other update the test code to
sync with the interface change.

  eal: improve interrupt handle
  test: update test code for interrupt callback change

The patch change the prototype of callback function
(rte_intr_callback_fn) by removing the unnecessary parameter.
Also with this change we can keep content of item in intr_source
read only, the inappropriate modifciation(like get_max_intr) can
be avoid.

The changes (to not change the interrupt handle in intr_sources) seems
to be unrelated to the API changes. Can you split this into two
commits, please?

Also I'm not 100% convinced that the low-level drivers should make
extensive use of the ethdev's const intr_handle. I believe that the
ethdev ops might be incomplete in that sense that it would be better
to add an rx_intr_ctl() operation to the ethdev ops structure and pass
control the the low-level device.

Yes, it's better to split this.

I agree your point, abstract the interrupt control should be good, but I want keep this
patch's scope to only focus on eal interrupt layer but not include the ethdev layer, 
there could be a separate patch focus on that.

It seems its not necessary to register an intr_handle for interrupt callback 
function. "void* cb_arg" shows enough when be used to pass the object that 
contain the information be required to handle the interrupt event( A typical
way which is implemented by almost all driver is by passing a rte_ethdev 
instance). The patch change the prototype of rte_intr_callback_fn by removing
the uncessary intr_handle paramter.

v2:
- seperate patch 1 in v1 into 2 patches
- correct some commit log.
