Subject: [dpdk-dev] [PATCH 05/15] vfio: generalize pci_vfio_set_iommu_type
Date: Fri, 29 Apr 2016 15:44:06 +0200	[thread overview]
Message-ID: <1461937456-22943-6-git-send-email-viktorin@rehivetech.com> (raw)
In-Reply-To: <1461937456-22943-1-git-send-email-viktorin@rehivetech.com>

The pci_vfio_set_iommu_type is not PCI-specific and it is a private function
of the eal_pci_vfio.c. We just rename the function and make it available even
for non-PCI devices.
