[dpdk-dev] [PATCH v3 2/2] net/i40e: fix Rx queue interrupt mapping in VF

2017-11-03 Thread Wei Dai
When a VF port is bound to VFIO-PCI, miscellaneous interrupt is mapped to MSI-X vector 0 and Rx queues interrupt are mapped to other vectors in vfio_enable_msix( ). To simplify implementation, all VFIO-PCI bound i40e VF Rx queue interrupts can be mapped in vector 1. And as current igb_uio only supp
