This patch mainly allocates structure to store queue/irq mapping, and configure queue/irq mapping down through PCI ops. It also creates eventfds for each Rx queue and tell the kernel about the eventfd/intr binding. Note: So far, we hard-code 1:1 queue/irq mapping (each rx queue has one exclusive interrupt), like this: vec 0 -> config irq vec 1 -> rxq0 vec 2 -> rxq1 ... which means, the "vectors" option of QEMU should be configured with a value >= N+1 (N is the number of the queue pairs).
