A high number of RX descriptor can be helpful in avoiding
packet loss due to the core being interrupted.
This commit increases the default number of descriptors from 256 to 2K.
Those values are checked versus the minimum and maximum supported by the pmd.
Number of mbufs (mempool size) have been updated n config files to support this
default number of dsescriptors.
The number of descriptors can still be overwritten by the config file. However
those values must always remain within the limits reported by the pmd.

Multicast can be enabled through configuration or through command line
- Through configuration
Add multicast=mcast_address (e.g. multicast=01:00:5e:01:02:03) in the port
section
- Through command line
run enable multicast port_id mcast_address (e.g. enable multicast 1 01:00:5e:01:02:03)
IGMP join message is sent unsollicited through command line:
join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3)
To enable swap answering IGMP Query (w/ IGMP Join)
- Through configuration
Add igmp ipv4=ip_address within the core/task section
- Through command line
join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3)
(this will 1st initiate an unsollicated join, then answer any subsequent query)
UDP/TCP packets received on a multicast address (224.0.0.0 => 239.255.255.255) are discarded
To stop sending responses to IGMP query:
leave igmp core_id task_id

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.

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.

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
