"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.
