+<p class="Pp">The ENA is a networking interface designed to make good use of
+ modern CPU features and system architectures.</p>
+<p class="Pp">The ENA device exposes a lightweight management interface with a
+ minimal set of memory mapped registers and extendable command set through an
+ Admin Queue.</p>
+<p class="Pp">The driver supports a range of ENA devices, is link-speed
+ independent (i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.),
+ and has a negotiated and extendable feature set.</p>
+<p class="Pp">Some ENA devices support SR-IOV. This driver is used for both the
+ SR-IOV Physical Function (PF) and Virtual Function (VF) devices.</p>
+<p class="Pp">The ENA devices enable high speed and low overhead network traffic
+ processing by providing multiple Tx/Rx queue pairs (the maximum number is
+ advertised by the device via the Admin Queue), a dedicated MSI-X interrupt
+ vector per Tx/Rx queue pair, and CPU cacheline optimized data placement.</p>
+<p class="Pp">The <code class="Nm">ena</code> driver supports industry standard
+ TCP/IP offload features such as checksum offload and TCP transmit
+ segmentation offload (TSO). Receive-side scaling (RSS) is supported for
+ multi-core scaling.</p>
+<p class="Pp">The <code class="Nm">ena</code> driver and its corresponding
+ devices implement health monitoring mechanisms such as watchdog, enabling
+ the device and driver to recover in a manner transparent to the application,
+ as well as debug logs.</p>
+<p class="Pp">Some of the ENA devices support a working mode called Low-latency
+ Queue (LLQ), which saves several more microseconds. This feature might be
+ implemented for the driver in future releases.</p>
