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 support only one vector, i40e VF PMD should use vector 0 for igb_uio and vector 1 for VFIO-PCI. Without this patch, VF Rx queue interrupt is mapped to vector 0 in register settings and mapped to VFIO vector 1 in vfio_enable_msix( ), and then all Rx queue interrupts will be missed. Also remove 2 unused macro definitions. Fixes: |
