2019-03-06PROX generator: performance optimization (2/4)Xavier Simonart8-162/+101
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. Change-Id: I1ce813d7e4ac1577ea412c590add5d6f94b36ec7 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2019-02-20Use link speed from device capability instead of negotiated speedaXavier Simonart4-13/+94
JIRA: SAMPLEVNF-151 link speed is used in gen and lat latency extrapolations. Using a link_speed value lower than the actual link speed might result in errors (e.g. negative latencies). Negotiated link speed might be reported slowly (as reported through irq) Hence it is better to use the device capability link speed. In addition, this remove the check for link speed changes in fastpath. Change-Id: I0f475fe5e139b046012de6cd0b710e4390735078 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2019-02-07Add check for configuration error (not enough mbuf)Xavier Simonart1-1/+24
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.

2019-01-30Fix memory leak in L3 submodeXavier Simonart2-1/+3
In L3 submodes, there were two memory leaks - when a L3 core was restarted, causing around 2MB leak and a potential issue after 256 start/stop - a potential mbuf leak when handling arp replies Those have been fixed Change-Id: I348478fa5967936297850432e93667e12b0adac4 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2019-01-28Add support for configurable arp timers in L3 modeXavier Simonart4-7/+26
L3 mode supports two timers: - arp_update_time, defaulted to 1 second, which makes PROX to send arp request every second for active flows - arp_timeout, previously defaulted to 30 seconds, which makes PROX consider a MAC address as invalid if no arp_reply was received within those 30 seconds. Those timers values were hardcoded. They can now be configured through the configuration file (within the core section), using resp. "arp update time" and "arp timeout" keywords. Unit is milli seconds. The default becomes respectively 1 second and 2 weeks. Change-Id: I35e46e97df32ca44c2cdfae85a20ee015de5d6e1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

RSS was enabled when rss=yes is set in the configuration or when multiqueue is being used. But when RSS was enabled the types of packets on which RSS hashing was applied might not be supported by the PMD, as almost every PMD supported a different set of packets.

2019-01-03Prevent dropping ARP packetsXavier Simonart5-13/+47
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>
2018-12-20Do not add count of non dataplane packets to dropped countXavier Simonart1-1/+6
RX packets count = TX count + dropped (handled + discarded) count + non dataplane packets count. Hence non dataplane packets such as unexpected packets (e.g. dhcp request) should not b considerded as handled.

2018-12-14Fix handing configuration error (missing tx port or ring in gen mode)Xavier Simonart1-1/+2
Gen mode requires a tx ring or a tx port. A configuration without those should gracefully report an error. This was causing a crash. Change-Id: Ia30d4d4c87a694da1dfed86587f90b9199c493ab Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-12-13Fix arp handling when master core is on socket 1Xavier Simonart1-1/+1
When master core was on socket 1, the rings setup to exchange messages related to arp between dataplane cores and master core was not properly setup, resulting in arp not working. Change-Id: Icc08df81f2e39e53de7c212248cdc7b78d7e2618 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-12-13Add support for zero packet loss in PROX L3 mode.Xavier Simonart3-24/+109
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.

2018-12-13Fix issue in l3 mode when no arp reply was receivedXavier Simonart1-7/+26
When no arp reply was received in l3 mode, the requesting core continuously sends ARP requests every seconds (which is correct). But master core was keeping a list of all requests, while all those requests are the same, resulting in potential table overflow.

2018-12-05Add support for VLAN insert and strippingXavier Simonart2-0/+19
JIRA: SAMPLEVNF-149 VLAN can be enabled on a port by adding "vlan=yes" in the port section. When VLAN is enabled on a port, then DEV_RX_OFFLOAD_VLAN_STRIP and DEV_TX_OFFLOAD_VLAN_INSERT are enabled (if device supports it). This will cause VLAN to be stripped from any packets received with the proper tag, and VLAN to be added for any packets being transmitted. The VLAN ID themselves are configured through the physical function using something like (where ens801f1 isthe PF): ip link set ens801f1 vf 0 vlan 1111 Change-Id: I945c87b0c18565da479ecaa08e5ffce91232a7ce Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
