Previously, the features list was indicating unsupported ENA PMD
features and were missing few ones, that were actually supported.
The features file was updated, so it is now reflecting current driver
state.
The documentation was updated with the more actual example and features,
especially ones which are ENA and not listed in the features file.

As of commit 364e08f2bbc0, DPDK allows an application to send and
receive raw packets using an AF_PACKET and PACKET_MMAP, when using
Linux Kernel. This complements it by adding a simple guide with the
following information:
- An introduction, where a brief explanation of this driver is given,
pointing out the dependency on PACKET_MMAP;
- Which options are supported at configuration time, while setting up an
interface, and it's inherent limitations;
- What the prerequisites are;
- A command line example of how to set up a DPDK port using the
af_packet driver.
Since there's a dependency in PACKET_MMAP, the guide also points to the
original Kernel documentation, so the reader can get more details.

The imissed counters (number of packets dropped because the queues were
full) were actually reported through xstats as "rx_out_of_buffer"
but was not reported through stats.
Following a recent discussion on the ML, as there is no way to tell the
user if a counter is implemented or not, this should be considered a
bug. For example, user looking at imissed will think the packets are
lost before reaching the device.

Previously, there is instability during vector Rx if descriptor
number is not power of 2, e.g. process hang and some Rx packets
are unexpectedly empty. That's because vector Rx mode assumes Rx
descriptor number is power of 2 when doing bit mask.
This patch allows vector mode only when the number of Rx descriptor
is power of 2.

Applications which add RSS rules must supply an RSS key and length.
If an application is only interested in default RSS operation it
should not care about the exact RSS key.
By setting the key to NULL - the PMD will use the default RSS key.
In addition if the application does not care about the RSS type it can
set it to 0 and the PMD will use the default type (ETH_RSS_IP).

A PMD parameter (rxq_cqe_pad_en) is added to enable 128B padding of CQE on
RX side. The size of CQE is aligned with the size of a cacheline of the
core. If cacheline size is 128B, the CQE size is configured to be 128B even
though the device writes only 64B data on the cacheline. This is to avoid
unnecessary cache invalidation by device's two consecutive writes on to one
cacheline. However in some architecture, it is more beneficial to update
entire cacheline with padding the rest 64B rather than striding because
read-modify-write could drop performance a lot. On the other hand, writing
extra data will consume more PCIe bandwidth and could also drop the maximum
throughput. It is recommended to empirically set this parameter. Disabled
by default.
