[dpdk-dev] [PATCH 0/2] eal: clean up interrupt handle

[Qi Zhang]

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.
