9a212dc06c doc: use code snippets in sample app guides
Currently the sample app user guides use hard coded code snippets,
this patch changes these to use literalinclude which will dynamically
update the snippets as changes are made to the code.
This was introduced in commit 413c75c33c ("doc: show how to include
code in guides"). Comments within the sample apps were updated to
accommodate this as part of this patch. This will help to ensure that
the code within the sample app user guides is up to date and not out
of sync with the actual code.

dcf384b4ff examples/l2fwd-crypto: support cipher multiple data-unit
The support for multiple data-units includes the next:
- Add a new command-line argument to provide the data-unit length.
- Set the length in the cipher xform.
- Validate device capabilities for this feature.
- Pad the AES-XTS operation length to be aligned to the defined data-unit.

b9f23beee0 examples/vhost: handle memory hotplug for async vhost
When the guest memory is hotplugged, the vhost application which
enables DMA acceleration must stop DMA transfers before the vhost
re-maps the guest memory.

To accomplish that, we need to do these changes in the vhost sample:
1. add inflight packets count.
2. add vring_state_changed() callback.
3. add inflight packets clear process in destroy_device() and
vring_state_changed().

74fb854a3d examples/l3fwd: remove useless reloads in LPM main loop
Number of rx queue and number of rx port in lcore config are constants
during the period of l3 forward application running. But compiler has
no this information.

Copied values from lcore config to local variables and used the local
variables for iteration. Compiler can see that the local variables are
not changed, so qconf reloads at each iteration can be eliminated.

The change showed 1.8% performance uplift in single core, single port,
single queue test on N1SDP platform with MLX5 NIC.

ca7036b4af vhost: fix offload flags in Rx path
The vhost library currently configures Tx offloading (PKT_TX_*) on any
packet received from a guest virtio device which asks for some offloading.

This is problematic, as Tx offloading is something that the application
must ask for: the application needs to configure devices
to support every used offloads (ip, tcp checksumming, tso..), and the
various l2/l3/l4 lengths must be set following any processing that
happened in the application itself.

On the other hand, the received packets are not marked wrt current
packet l3/l4 checksumming info.

Copy virtio rx processing to fix those offload flags with some
differences:
- accept VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP,
- ignore anything but the VIRTIO_NET_HDR_F_NEEDS_CSUM flag (to comply with
  the virtio spec),

Some applications might rely on the current behavior, so it is left
untouched by default.
A new RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS flag is added to enable the
new behavior.

The vhost example has been updated for the new behavior: TSO is applied to
any packet marked LRO.

783768136f pipeline: auto-detect endianness of action arguments
Each table entry is made up of match fields and action data, with the
latter made up of the action ID and the action arguments. The approach
of having the user specify explicitly the endianness of the action
arguments is difficult to be picked up by P4 compilers, as the P4
compiler is generally unaware about this aspect.

This commit introduces the auto-detection of the endianness of the
action arguments by examining the endianness of the their destination:
network byte order (NBO) when they get copied to headers and host byte
order (HBO) when they get copied to packet meta-data or mailboxes.

The endianness specification of each action argument as part of the
rule specification, e.g. H(...) and N(...) is removed from the rule
file and auto-detected based on their destination. The DMA instruction
scope is made internal, so mov instructions need to be used. The
pattern of transferring complete headers from table entry action args
to headers is detected, and the associated set of mov instructions
plus header validate is internally detected and replaced with the
internal-only DMA instruction to preserve performance.

9510dd1feb examples/l3fwd: add FIB infrastructure
The purpose of this commit is to add the necessary function calls
and supporting infrastructure to allow the Forwarding Information Base
(FIB) library to be integrated into the l3fwd sample app.
Instead of adding an individual flag for FIB, a new flag '--lookup' has
been added that allows the user to select their desired lookup method.
The flags '-E' and '-L' have been retained for backwards compatibility.

da796d2755 examples/l3fwd: move routes to common header
To prevent code duplication from the addition of lookup methods
the routes specified in lpm should be moved to a common header.

0c74a91ad6 examples/l3fwd: fix LPM IPv6 subnets
Any IP within the 2001:200::/48 subnet will match all the routes given
instead of 1 individual route and the application cannot
differentiate between them.
The change in this patch allows the ports to be individually matched using
smaller /64 ranges for each port. These smaller subnet ranges are still
within the 2001:200::/48 subnet range set aside for benchmarking
in RFC5180.
l3fwd will now use 2001:200:0:{0-7}::/64 where 0-7 is the port ID for IPv6.
