+GVE poll mode driver
+=======================
+
+The GVE PMD (**librte_net_gve**) provides poll mode driver support for
+Google Virtual Ethernet device (also called as gVNIC).
+
+Current gVNIC is an alternative to the virtIO-based ethernet interface that can
+support higher network bandwidths such as the 50-100 Gbps speeds.
+Large receive offload (LRO) is currently not supported.
+Please refer to https://cloud.google.com/compute/docs/networking/using-gvnic
+for the device description.
+
+The base code is under MIT license and based on GVE kernel driver v1.3.0.
+GVE base code files are:
+
+- gve_adminq.h
+- gve_adminq.c
+- gve_desc.h
+- gve_desc_dqo.h
+- gve_register.h
+- gve.h
+
+Please refer to https://github.com/GoogleCloudPlatform/compute-virtual-ethernet-linux/tree/v1.3.0/google/gve
+to find the original base code.
+
+GVE has 3 queue formats:
+
+- GQI_QPL - GQI with queue page list
+- GQI_RDA - GQI with raw DMA addressing
+- DQO_RDA - DQO with raw DMA addressing
+
+GQI_QPL queue format is queue page list mode. Driver needs to allocate
+memory and register this memory as a Queue Page List (QPL) in hardware
+(Google Hypervisor/GVE Backend) first. Each queue has its own QPL.
+Then Tx needs to copy packets to QPL memory and put this packet's offset
+in the QPL memory into hardware descriptors so that hardware can get the
+packets data. And Rx needs to read descriptors of offset in QPL to get
+QPL address and copy packets from the address to get real packets data.
+
+GQI_RDA queue format works like usual NICs that driver can put packets'
+physical address into hardware descriptors.
+
+DQO_RDA queue format has submission and completion queue pair for each
+Tx/Rx queue. And similar as GQI_RDA, driver can put packets' physical
+address into hardware descriptors.
+
+Please refer to https://www.kernel.org/doc/html/latest/networking/device_drivers/ethernet/google/gve.html
+to get more information about GVE queue formats.
+
+Features and Limitations
+------------------------
+
+In this release, the GVE PMD provides the basic functionality of packet
+reception and transmission.
+
+Currently, only GQI_QPL and GQI_RDA queue format are supported in PMD.
+Jumbo Frame is not supported in PMD for now. It'll be added in the future
+DPDK release.
+Also, only GQI_QPL queue format is in use on GCP since GQI_RDA hasn't been
+released in production.
