2018-12-13Add support for zero packet loss in PROX L3 mode.Xavier Simonart1-21/+82
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 Simonart1-2/+0
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>
2018-10-28Add support for counting non dataplane related packetsXavier Simonart1-0/+1
When performing some zero packet loss performance testing on dataplane, it is important (not) to count non dataplane packets. For instance, one might receive uexpected packets from a switch, or ARP packets. Or one might need to transmit ARP packets. Such packets should not be counted as dataplane packets as for thse packets there is no 1:1 mapping between transmitted packets and received packets. To support this, the counters reporting numbers of transmitted and received packets remain unchanged but two new counters have been added to PROX, counting respectively number of received and number of transmitted non-dataplane packets. On RX side, packets are counsidered as non-dataplane if being ARP or if they do not countain the proper signature On TX side, ARP packets are not considered as dataplane packets. This feature requires configuration of signature. "dp core stats" command has been added Change-Id: I98e113cd02f36d540383d343a433592867ad86a9 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
