+Descriptor Formats

+GVE supports two descriptor formats: GQI and DQO. These two formats have
+entirely different descriptors, which will be described below.

 Registers

+All registers are MMIO.
 
 The registers are used for initializing and configuring the device as well as
 querying device status in response to management interrupts.
 
+Endianness

+- DQO descriptors and datapath registers are Little Endian.

 The buffers for receive rings are put into a data ring that is the same
 length as the descriptor ring and the head and tail pointers advance over
 the rings together.

+DQO Traffic Queues
+------------------
+- Every TX and RX queue is assigned a notification block.
+
+- TX and RX buffers queues, which send descriptors to the device, use MMIO
+  doorbells to notify the device of new descriptors.
+
+- RX and TX completion queues, which receive descriptors from the device, use a
+  "generation bit" to know when a descriptor was populated by the device. The
+  driver initializes all bits with the "current generation". The device will
+  populate received descriptors with the "next generation" which is inverted
+  from the current generation. When the ring wraps, the current/next generation
+  are swapped.
+
+- It's the driver's responsibility to ensure that the RX and TX completion
+  queues are not overrun. This can be accomplished by limiting the number of
+  descriptors posted to HW.
+
+- TX packets have a 16 bit completion_tag and RX buffers have a 16 bit
+  buffer_id. These will be returned on the TX completion and RX queues
+  respectively to let the driver know which packet/buffer was completed.
+
+Transmit
+~~~~~~~~
+A packet's buffers are DMA mapped for the device to access before transmission.
+After the packet was successfully transmitted, the buffers are unmapped.
+
+Receive
+~~~~~~~
+The driver posts fixed sized buffers to HW on the RX buffer queue. The packet
+received on the associated RX queue may span multiple descriptors.
