The "Latency" screen has been updated with 3 columns:
- mis-ordered
Count the number of mis-ordered packets.
- extent:
Gives an indication of how mis-ordered the packets are.
Receiving packet "x - 5" after receiving packet "x" will
cause an extent of 5.
- duplicate:
Count number of duplicate packets.
Following commands have been added for the impair mode:
- proba no drop: replaces the former "probability" command.
Percentage of forwarded packets. So 99.5 means 0.5% of packet drop.
- proba delay
Percentage of delayed packets for the impair mode.
- proba duplicate
Percentage of duplicate packets.
Similar parameters are supported within the config files:
- proba no drop
- proba delay
- proba duplicate
Note: it is recommanded to use the signature when measuring packet
misorder, as otherwise unexpected packet would cause miscounts.

- Latency Distribution (i.e. histograms) has been added when latency is enabled.
- Histograms are now compiled by default.
- A bug has also been fixed, which was causing strange behavior in the histograms
(due to bucket size being overwritten).
- The default bucket size has been changed to "11" which means that the size of each bucket
is now (1 cycle << 11) = 2048 cycles = 1 microsecond at 2GHz. It was (1 << (10 - 1)).
As there are 128 latency buckets, it is not possible to show all of them on the display.
Hence the latency buckets are displayed based on on the assumption that the minimum latency is usually relatively
stable and that the maximum latency change more often.
- The first empty buckets are not shown (i.e. buckets empty for all tasks)
- If more than 15 buckets are non empty, then the buckets are combined, so that a maximum of
15 (bigger) buckets are shown
- If less than 15 buckets are non empty, the following (empty) buckets are shown
(this avoid seeing every x seconds some columns being added and removed).

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
