When the following conditions are met:
- ipv4
- vdev enabled
Then multiple vlans are supported.
Multiple vlans can be configured using the vlan_tag option within the port section of the config file.
Multiple (different) local_ipv4/prefix must then also be configured within the same section.
Note that for ipv6 multiple vlans are not supported (yet)
Also, when vdev is not enabled, multiple vlans are also not (yet) supported.

- vdev devices now support VLAN.
- kernel tap device can be configured with a netmask (/24 was
always used in previous version).
- when sending a (fake) packet to the kernel, this packet will now
not be routed by the kernel (i.e. it will leave through the
interface configured by PROX). This might change in the futture
when PROX supports multiple VLANs per port. But today it prevents
ARP being sent on management interfaces.
- Log error in case kernel unable to send packet.
- Added support for comments (';') in lua sections.
- Prevent duplication of local_ipv4 - should now be configured in port section
local_ipv4 in core section still supported

Following messages are now handled by PROX
- router_solicitation
- neighbour_solicitation
- router_advertisement
- neighbour_advertisement
The following parameters are supported (through the PROX config file)
- sub mode=ndp
This will enable handling of router and neighbour solicitation
and advertisement.
- local ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx
This will configure the local IPv6 address of the port.
This parameter is optional. If not specified, the local IPv6
will be calculated from the EUI.
- global ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx
This will configure the global IPv6 address of the port.
This parameter is optional. If not specified, the global IPv6
will be calculated from the EUI and the router prefix received
from the router.
- ipv6 router=yes
This will cause the core to behave as an IPv6 router
i.e. it will generate Router Advertisement messages
This is only useful in back to back cases, when no real
IPv6 router is present in the setup.
- router prefix=xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
The router prefix usedin the router advertisement
The prefix will be used by the node to build an IPv6 global
address in cases none were configured.
"Unsollicited NA" parameter has been added within the core/task section.
If set to yes (Unsollicited NA=yes), then an unsollicited neighbour
Advertisement is sent at startup
A same core/task cannot support both l3 and ndp mode.
Those messages will be generated or handled when submode
is set to "ndp":
- neighbour sollicitation
- neighbour advertisement
- router sollicitation
- router advertisement
An example configuration is provided: config/ipv6.cfg in which
port 0 / core 1 plays the role of the generator and port 1 /
core 2 plays the role of the swap.

This commit prepares PROX for supporting changes from DPDK 19.08
Mainly, the "sed" listed below were run.
In addition,
- some forward definition have been removed,
- prox_compat.h has been updated
- prox_compat.h has been included where necessary.
Hence such a commit is rather easy to review and to reapply
on other branches if necessary.

fb0c44a fixed compilation on GCC 8 by using:
1) #pragma GCC diagnostic ignored "-Wstringop-truncation"
2) __attribute__ ((fallthrough));
However, -Wstringop-truncation has only been introduced in GCC 8 and
__attribute__ ((fallthrough)) has only been introduced in GCC 7.
Hence they caused Warnings/Errors on earlier versions.
Comments about fallthough (see https://developers.redhat.com/blog/2017/03/10/wimplicit-fallthrough-in-gcc-7/)
can be used on GCC 8 to prevent fall through warnings

The "dp core stats" command supported, as other commands, multiple cores
but not multiple tasks. It now supports both (e.g. dp core stats 1-2 0-1).
This is necessary so that users can collect all statistics from PROX in one
command line.
It will return similar information on the screen or through the socket:
- if the syntax is wrong (e.g. missing task, too many cores or tasks, ...)
=> an error message is printed on the screen, and the single error line
"error: invalid syntax" is returned through the socket
- if the syntax is correct
=> one line is printed or returned for each core/task pair
=> if the core/task pair is invalid, the line reports an error
=> otherwise, the line provides dataplane statistics for the core/task pair,
with the core_id and task_id added, either at the end of the line returned
through the socket, or at the beginning of the line printed on the screen.
This means a change in behaviour when using the socket: before, when an error
happened (e.g. bad task), then nothing was returned which made it difficult for
the script to catch the syntax error.
Similar behaviour could/should be implemented for other commands.
However, care must be taken as some scripts like NSB might count the number
of lines within the output, or the number of items within the line.
This should not be an issue for dp core stats as NSB does not use it, and other
PROX scripts do not count the number of items and will be adjusted to count the
number of lines.

This feature will enable the possibility to have many cores
configured in a prox config file, and enable/disable them
through variables.
For instance, a [core $var1] section in a config file will
result in [core 1] if $var1 = 1; the whole section and section
content will be ignored if $var1=#
Before this implementation, [#core 1] or [core #] was already
treated as a commented out section (the whole section was
commented). But there was no way to define a variable $var = #
to comment a section through a variable.
Note that in today's implementation any non numerical
(except s, h, t, -) characteter in the [core] section header
(and not only #) will cause the section to be ignored.
It would probably be better to consider # (as maybe N/A and none)
as comments, and everything else as error. This is however not
supported by the change request.

JIRA: SAMPLEVNF-55
PROX is a DPDK-based application implementing Telco use-cases such as
a simplified BRAS/BNG, light-weight AFTR... It also allows configuring
finer grained network functions like QoS, Routing, load-balancing...
(We are moving PROX version v039 to sampleVNF
