[dpdk-dev] [PATCH v3 0/5] raw/ifpga/base: An improvement for multi-process

[Tianfei zhang <tianfei.zhang@intel.com>]

This patches set will improve the ifpga base driver reliability in
multi-process environment.

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.
