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.
v6:
- Sync with latest test code.
v5:
- Update mlx4 driver which is missed in previous version.
v4:
- Update mlx5 driver which is missed in v1, v2, v3.
- Add back patch 1 of v2 to make this complete though it already be applied.
- Remove patch 3 which is not necessary with latest master.
v3:
- Update bnx2x driver which is missed in v1,v2
v2:
- Seperate patch 1 in v1 into 2 patches.
- Correct some commit log.

Remove the inappropriate modification on get_max_intr
field that keep the intr_source read only.

Pasting some comments from previous versions:
* You forgot to use --in-reply-to, so it is not convenient to check the history.
* Please keep the the prior acked-by in your patches if there are.
(if think there was a ack for vfio)
* The test patch should be squashed with eal/drivers changes.
New comment:
* New drivers has been added, please rebase and update them.

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.
v7:
- Update for avp and tap driver which are new added
- Merge patch 2 and 3 of v6.
v6:
- Sync with latest test code.
v5:
- Update mlx4 driver which is missed in previous version.
v4:
- Update mlx5 driver which is missed in v1, v2, v3.
- Add back patch 1 of v2 to make this complete though it already be applied.
- Remove patch 3 which is not necessary with latest master.
v3:
- Update bnx2x driver which is missed in v1,v2
v2:
- Seperate patch 1 in v1 into 2 patches.
- Correct some commit log.
