91d3e2d429 examples/vhost_blk: refactor to increase readability
Refactor the code and make it easier to read. It's
useful for understanding the inflight APIs and how
packed ring works. Update the RST because the packed
ring patch has been merged to QEMU master and ring_packed
parameter changes to packed.

092454d999 examples/l2fwd-event: add option to configure port pairs
Current l2fwd-event application statically configures adjacent ports as
destination ports for forwarding the traffic.

Add a config option to pass the forwarding port pair mapping which allows
the user to configure forwarding port mapping.

If no config argument is specified, destination port map is not
changed and traffic gets forwarded with existing mapping.

To align port/queue configuration of each lcore with destination port
map, port/queue configuration of each lcore gets modified when config
option is specified.

Ex: ./l2fwd-event -c 0xff -- -p 0x3f -q 2 --config="(0,3)(1,4)(2,5)"

With above config option, traffic received from portid = 0 gets forwarded
to port = 3 and vice versa, similarly traffic gets forwarded on other port
pairs (1,4) and (2,5).

Inline processing is limited to a specified subset of traffic. It is
often unable to handle more complicated situations, such as fragmented

Introduce fallback session for inline crypto processing allowing

configured by adding 'fallback' keyword with 'lookaside-none' parameter
to an SA configuration. Only 'inline-crypto-offload" as a primary
session and 'lookaside-none' as a fall-back session combination is
supported by this patch.

Fallback session feature is not available in the legacy mode.

b01d1cd213 examples/ipsec-secgw: support fragmentation and reassembly
Add optional ability to fragment packet bigger then mtu,
and reassemble fragmented packet.
To minimize possible performance effect, reassembly is
implemented as RX callback.
To support these features ipsec-secgw relies on librte_ipsec ability
to handle multi-segment packets.
Also when reassemble/fragmentation support is enabled, attached
crypto devices have to support 'In Place SGL' offload capability.
To enable/disable this functionality, two new optional command-line
options are introduced:
  --reassemble <val> - number of entries in reassemble table
  --mtu <val> - MTU value for all attached ports
As separate '--mtu' option is introduced, '-j <val>' option is now used
to specify mbuf data buffer size only.

609e79841f examples/l3fwd-power: add telemetry mode
Add new telemetry mode support for l3fwd-power.
This is a standalone mode, in this mode l3fwd-power
does simple l3fwding along with calculating
empty polls, full polls, and busy percentage for
each forwarding core. The aggregation of these
values of all cores is reported as application
level telemetry to metric library for every 500ms from the
master core.

The busy percentage is calculated by recording the poll_count
and when the count reaches a defined value the total
cycles it took is measured and compared with minimum and maximum
reference cycles and busy rate is set according to either 0% or
50% or 100%.

cd1dadeb9b examples/rxtx_callbacks: support HW timestamp
Use rxtx callback to demonstrate a way to use rte_eth_read_clock to
convert the hardware timestamps to an amount of cycles.

This allows to get the amount of time the packet spent since its entry
in the device. While the regular latency only shows the latency from
when it entered the software stack.

Since we change these macros, we might as well avoid triggering complaints

ea6b39b5b8 kni: remove ethtool support
Current design requires kernel drivers and they need to be probed by
Linux up to some level so that they can be usable by DPDK for ethtool
support, this requires maintaining the Linux drivers in DPDK.

Also ethtool support is limited and hard, if not impossible, to expand
to other PMDs.

Since KNI ethtool support is not used commonly, if not used at all,
removing the support for the sake of simplicity and maintenance.
