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.

In Prox configuration IMIX can be specified using the following syntax:
imix=pkt_size,pkt_size... Up to 127 different pkt sizes can be specified.
Through command line, the following syntax can be used
imix core_id task_id pkt_size,pkt_size... Up to 127 packet sizes can be specified.
When IMIX is enabled, PROX will loop through the list of packet sizes.
PROX supports two different submodes to handle pcap files.
In the 1st submode (default, no submode specified), timestamps from
the pcap file are ignored. In this submode IMIX is supported as well and each
packets in the pcap file will be generated with all IMIX sizes.
In the second submode, called pcap in gen mode, packets are generated at
the timestamp specified in the pcap file. This submode does not support IMIX.

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.

- When using "pcap file" argument in PROX config file in the gen mode
(and no submode), packets were truncated to 8 bytes (and a warning printed)
This has been fixed.
- "Set value" command was checking whether offset was within first 1518 bytes
unrespective to the mtu (e.g. jumbo packets). This has been fixed.
- There was a limit of 64K packets loaded from a pcap file (which could be
overwritten through PROX config). This limit has been removed - by default
all packets from pcap are loaded
- When pcap was loaded, memory was allocated to store the packet. However
just enough memory was allocated, so that there was no way to change (increase)
packet size through command line after that. Now memory is allocated to store
up to mtu size
- While "set value" command was acting on all packets, "pkt size" command
was only changing the first packet. This has now been changed and both commands
change all the packets.
- A few other minor cleanups.

In addition to resetting all values set by the user, reset value was also
resetting internal configuration. It resulted that the src mac address
in the outgoing packet was set to whatever was specified in pkt inline,
which is wrong (by default src mac address should be set the the port mac address).
Note that reset value reset any "set values" but does not reset
the packet size.

Accuracy of latency is obtained by writing TX accuracy for packet N
in a later packet i.e. packet N + WINDOW.
If this window is too small, packet N + WINDOW (conveying accuracy
for packet N) might arrive before packet N, resulting in no accuracy
for packet N.
This change increases this window from 64 to 8K packets.
This change should result in a higher number of packets used for
latency measurements when packets are reordered.
This change might have a performance impact as it uses more memory.

When PROX fails to transmit packets (e.g. because switch or NIC
is overloaded) some cleanup needs to be done related to packet id
and latency.
In addition, in some casesi, the clock estimate is slighly over-estimated
which might result, in rare cases, in negative (hence very high) latencies,
due to the extrapolation of timestamps.
This has been workarounded bydecreasing the extrapolation, tolerating up to 1%
clock estimate error

Improve PROX generator performance by pre-calculating bytes_to_tsc.
This improvement is only implemented for non-pcap
generator, where only few different packet sizes are usually generated.
This change might have a negative performance impact in some cases, if
many different packet sizes are generated, resulting in higher memory usage.
This is the case for instance if random is applied to packet size.
In addition, simplified the rx path, receiving now only MAX_PKT_BURST packets
per handle loop.
Before we were trying to empty the NIC looping on RX packets, ending up
with many rx packets per handle loop. This was used to determine an lower bound
for the time the packet was received.
We now set the lower bound when less than MAX_PKT_BURST has been received.

JIRA: SAMPLEVNF-151
link speed is used in gen and lat latency extrapolations.
Using a link_speed value lower than the actual link speed
might result in errors (e.g. negative latencies).
Negotiated link speed might be reported slowly (as reported through irq)
Hence it is better to use the device capability link speed.
In addition, this remove the check for link speed changes in fastpath.

Gen mode requires a tx ring or a tx port. A configuration without those
should gracefully report an error. This was causing a crash.

mbuf size was setup to achieve the best performance i.e.
using the smallest mbuf and not segmenting packets.
However this resulted in complex code, much dependent of the way
the pmd are working e.g. a change(fix) in recent dpdk i40e
implementation caused a 1782 (=1518+8+256) bytes mbuf to be too
small to hold a 1518 bytes packets.
Hence this change simplifies the mbuf size selection at the price
of a potential decreases in performance - as more memory is now used.
Except if jumbo frames are used, the mbuf size will now be the same
for all modes. The packets will not be segmented except if jumbo
frames are enabled.
If jumbo frames are enabled, packets are by default segmented, except
if the mbuf size is configured big enough in the config file.

When link is down at startup, the link_speed returned by DPDK
is 0. This results in un-optimized latency estimates in gen and lat.
With this fix, lat and gen do nothing until link_speed is
properly initialized, and use the right link speed in the fast path.

Link_speed could be null when prox started with the ports down.
This was potentially causing a crash.
Another task will need to update link speed when the port come
up. Failing to do this results in less accurate latencies
(no extrapolation)

- Also changed lat_info.tx_packet_index to uint64_t,
so also did it for task_lat.prev_tx_packet_index and n_loss.
- Adjusted format strings accordingly, and fixed some other formats.
- Adjusted overflow increment to 2^32 (i.e. UINT32_MAX + 1).
- Replaced hard-coded 64 with ACCURACY_BUFFER_SIZE (still hard-coded
in handle_gen.c).

When doing latency measurements PROX takes into account the
generation or reception of a bulk of packets. For instance, if
PROX receives at time T 4 packets, it knows that the first
packet was received by te NIC before T (the time to receive the other
3 packets, as they were received at maximum link speed).
So the latency data is decreased by the minimum time to receive those
3 packets.
For this PROX was using a default link speed of 10Gbps. This is wrong
for 1Gbps and 40Gbps networks, and was causing for instance issues
on 40 Gbps networks as extrapolating too much, resulting in either
too low latencies or negative numbers (visible as very high latencies).

Different checks were done when setting the generator pkt_size.
In case of wrong pkt_size (e.g. too big) an error was printed but
the pkt_size was still set causing a potential corruption.
In addition, in case of a packet size incompatible with some
of the packet fields (e.g. latency data) PROX was panicing
while this should not happen runtime for such an error.
