+=====================
+One-shot Rx Interrupt
+=====================
+One-shot Rx interrupt feature will split rx interrupt handling from other
+interrupts like LSC interrupt. It implemented one handling mechanism to
+eliminate non-deterministic DPDK polling thread wakeup latency.
+
+VFIO' multiple interrupt vectors support mechanism to enable multiple event fds
+serving per Rx queue interrupt handling.
+UIO has limited interrupt support, specifically it only support a single
+interrupt vector, which is not suitable for enabling multi queues Rx/Tx
+interrupt.
+
+Prerequisites
+=============
+Each of the 10Gb Ethernet* ports of the DUT is directly connected in
+full-duplex to a different port of the peer traffic generator.
+
+Iommu pass through feature has been enabled in kernel.
+ intel_iommu=on iommu=pt
+
+Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d
+in bios. When used vfio, requested to insmod two drivers vfio and vfio-pci.
+
+Test Case1: PF interrupt pmd with uio
+=====================================
+Run l3fwd-power with one queue per port::

+waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq0
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers

+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers

+
+Send packet with increased dest IP to Port0 and Port1, check that thread on
+core1,core2,core3,core4 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq1
+ L3FWD_POWER: lcore 3 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 4 is waked up from rx interrupt on port1,rxq1
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1,core2,core3,core4 will return to

> +One-shot Rx Interrupt
> +=====================
> +One-shot Rx interrupt feature will split rx interrupt handling from
> +other interrupts like LSC interrupt. It implemented one handling
> +mechanism to eliminate non-deterministic DPDK polling thread wakeup latency.
> +
> +VFIO' multiple interrupt vectors support mechanism to enable multiple
> +event fds serving per Rx queue interrupt handling.
> +UIO has limited interrupt support, specifically it only support a
> +single interrupt vector, which is not suitable for enabling multi
> +queues Rx/Tx interrupt.
> +
> +Prerequisites
> +=============
> +Each of the 10Gb Ethernet* ports of the DUT is directly connected in
> +full-duplex to a different port of the peer traffic generator.
Please add more description as below:
Assume PF port PCI addresses are 0000:08:00.0 and 0000:08:00.1, their
Interfaces name are p786p1 and p786p2.
Assume generated VF PCI address will be 0000:08:10.0, 0000:08:10.1.

> +Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and

I'm not sure about the format, but the last line should not be here.
