Main changes from v2: - Fix typo in some commit log. Main changes from v3: - Split into 2 small patches, one is fix the pointer variable, other is fix the return value. - Free the driver's resource in rawdev close ops. Patch #1: Fix a bug for register and unregister interrupt functions. Patch #2: Fix the return value of unsupported interrupt type. Patch #3: Fix the return value of ifpga_unregister_msix_irq(), because rte_intr_callback_unregister() can return positive as success. Patch #4: Clean up the ifpga resource when close the application. Patch #5: An improvement of the concurrent in multi-process operation. A share memory mechanism and some new mutex will be used for multi-process protection.
