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.

A virtual device can be created adding the following option on the eal field within
the eal options section:
--vdev=net_ring0
This will cause a new (virtual) dpdk port to be created.
Such a device can then be used in a primary process as other DPDK devices i.e.
a [port x] section must be defined in the configuration file
For a secondary process, there is no need to add --vdev, but, of course
--proc-type=secondary (or --proc-type=auto) must be set within the eal field.
There are two ways to use such a virtual device in a secondary process
1) Using the DPDK port number. Note however that the DPDK port number of virtual devices
in the secondary process might not start from 0 and might hence have to be guessed
e.g. if using 2 virtual devices in primary process (--vdev=net_ring0 --vdev=net_ring1)
the port_id will be 0 and 1 in primary process and 2 & 3 in secondary process.
2) Using the port name, as defined in --vdev in the primary process. In this way,
no [port] section must be defined, and the virtual port names are directly used within
the "rx port" and "tx port" configuration e.g.:
rx port=net_ring0
tx port=net_ring1
Limitations
===========
There seems to be a PROX leak causing DPDK port id to increase when restarting the
secondary process (causing the secondary process configuration through port id more difficult).
As the primary process configures the port (including the number of rx and tx queues)
based on its config file, the secondary process can't setup its own queues.
Simple configurations (such as using gen or lat in primary, and swap in secondary) work as PROX
allocates a RX queue even in gen mode and a TX queue even in lat mode. Better configuration/support
for secondary process should be designed.
The use of dpdk port names is only supported by PROX within "rx port" and "tx port". It is not
supported by other configuration fields such as "tx ports from routing table".
The use of dpdk port names in "rx port" and "tx port" is limited to only 1 port.

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.

On recent OSes such as RHEL 8.0, ncurses(6.1) introduced support
for ECMA-48 repeat character control.
Some terminal emulators use TERM=xterm but do not support this feature.
In this case, printing repeated character such as "22000000 Hz" might
be displayed as 220 Hz.
Other emulators, such as tmux, use TERM=screen, and do not exhibit the issue.

PROX version was not udpated since a long time, resulting in
difficulty to easily understand which version is being run.
Improved solution should be to support sha1.

Number of mbufs must at least cover for number of rx descriptors,
number of tx descriptors, number of mbuf cached and number of
mbufs handled by the application.
If this is not the case, a warning is returned.
This ony check for the more basic cases. This will not check for
instance for cases with multiples rings where more mbufs might be
cached.

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 configuring a port, prox configures queue flags.
For historitical reasons, offloads had to be disabled on
some pmds.
There is now an API to query the ports and gets their
capabilities. This fix sets now the flags based on the capabilities,
and not the driver name.

Jumbo frames are now supported through the addition of a "mtu"
parameter of the port in the config file.
Setting the mtu to a value higher than 1500 bytes will enable
the reception of jumbo frames.
In addition, the rte_eth_dev_set_mtu is now set for all pmds.
Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD
anymore. This option was only used for pure debugging.
Big packets can be received using two ways
- Using multiple "small" mbufs, i.e. around 2K. This is the default.
- Using one big mbuf holding the whole packet. This can be enabled
by setting a parameter mbuf_size in the receiving core configuration

This adds support for tasks in l3 submode receiving from ports but
transmitting to rings.
ARP related information is exchanged between tasks through master core.
Tasks transmitting to physical ports are responsible to transmit arp
related packets. Tasks not transmitting to physical ports (and using
rings) should not try to transmit arp packets. Transmitting arp
packets through ring would be more complex, as we would need extra information
(within the mbuf) to distinguish for instance an arp reply comoing from the
network and an arp reply coming from a core (as a reply to an arp request).

The l3 submode was not supported in nop mode, as the nop mode uses some
specific nop thread (and not generic). When L3 is specified, the nop mode
must use the generic thread. In addition the l3 submode is implemented
differently than other submodes. It is not supported through task_init
structures (i.e. each task does not have to explicitely tell that it
supports l3 submode). But this prevented to run both a nop with no submode
and a nop with a l3 submode. Note that nop with l3 is usually not very useful
- it handles arp (requests and response) but as nop, it does not swap IP
addresses. So with a real switch, the packets transmitted will be received
back... and l3 mode is usually mainly usefull when using a switch.
However, there is at least one nop mode where l3 submode makes sense:
when the nop does not transmit. In such cases, for instace used in
conjunction with a gen l3, the nop receives all packets and forward
the arp requests and responses to the master for handling.
