2019-01-03Prevent dropping ARP packetsXavier Simonart1-0/+33
JIRA: SAMPLEVNF-152 When system is overloaded, ARP packets were sometimes dropped, as any other packets. This was causing two issues: - The count of TX non dataplane packets was wrong - If many consecutive ARP packets were dropped, the underlying switch might see its ARP timer expiring, causing performance degradation (packets being broadcasted). ARP packets are now always sent as no-drop. Change-Id: I9a86cbf8c4b56a178f86bc789153f1fa49ddf73f Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-12-13Add support for zero packet loss in PROX L3 mode.Xavier Simonart1-3/+20
In L3 mode, prox is extracting IP destination address in the packets. It uses this destination address to find the MAC address. If the MAC address is not found, it sends a ARP request. It also sends ARP request when it realizes that some timeout expired. However, PROX was using the mbuf of the existing packets (to be forwarded) to send the ARP. This resulted in packet loss. Now PROX is generating ARP requests using mbuf from an ARP mempool. Some clean up was also done.

2018-12-13Clean up debugging messagesXavier Simonart1-4/+4
Print IP address in a.b.c.d format instead of one 32-bit number. Better align debugging information in log file Change-Id: Icfab30836ba83d53f700fcfbdfbd7cf238ed7bf8 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-02-13Fix potential crash in rx and tx distributionXavier Simonart1-1/+4
In some (rare) modes, more than 64 packets can be received through one rx function. This is for instance the case of the lat mode. Change-Id: Ie733c927a8e116c679c464f2551768185ef85366 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2017-07-14Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNFDeepak S1-0/+665
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 https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S <deepak.s@linux.intel.com>
