[dpdk-dev] [PATCH v3 2/5] raw/ifpga/base: handle unsupported interrupt type

[Tianfei zhang]

From: Wei Huang <wei.hu...@intel.com>

Handle unsupported interrupt type requests properly,
on unsupported interrupt case:
'ifpga_unregister_msix_irq()' returns success,
'ifpga_register_msix_irq()' return failure.

Fixes: e0a1aafe ("raw/ifpga: introduce IRQ functions")
Cc: sta...@dpdk.org
