2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart1-41/+41
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.

2018-04-26Fix crc offloads.Xavier Simonart1-4/+4
When configuring a port, prox configures queue flags. For historitical reasons, offloads had to be disabled on some pmds. There is now an API to query the ports and gets their capabilities. This fix sets now the flags based on the capabilities, and not the driver name. Change-Id: Ic72d15001992f26910f653c70d31e4381fff8089 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-04-15Add support for reception of jumbo framesXavier Simonart1-33/+63
Jumbo frames are now supported through the addition of a "mtu" parameter of the port in the config file. Setting the mtu to a value higher than 1500 bytes will enable the reception of jumbo frames. In addition, the rte_eth_dev_set_mtu is now set for all pmds. Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD anymore. This option was only used for pure debugging. Big packets can be received using two ways - Using multiple "small" mbufs, i.e. around 2K. This is the default. - Using one big mbuf holding the whole packet. This can be enabled by setting a parameter mbuf_size in the receiving core configuration Change-Id: Idd60ad31f41c89f9522dff4d894af2696b7a2ea1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2017-12-18Add l3 support for tasks without physical tx portsXavier Simonart1-6/+3
This adds support for tasks in l3 submode receiving from ports but transmitting to rings. ARP related information is exchanged between tasks through master core. Tasks transmitting to physical ports are responsible to transmit arp related packets. Tasks not transmitting to physical ports (and using rings) should not try to transmit arp packets. Transmitting arp packets through ring would be more complex, as we would need extra information (within the mbuf) to distinguish for instance an arp reply comoing from the network and an arp reply coming from a core (as a reply to an arp request).

2017-11-15Add support for nop mode with l3 submodeXavier Simonart1-7/+31
The l3 submode was not supported in nop mode, as the nop mode uses some specific nop thread (and not generic). When L3 is specified, the nop mode must use the generic thread. In addition the l3 submode is implemented differently than other submodes. It is not supported through task_init structures (i.e. each task does not have to explicitely tell that it supports l3 submode). But this prevented to run both a nop with no submode and a nop with a l3 submode. Note that nop with l3 is usually not very useful - it handles arp (requests and response) but as nop, it does not swap IP addresses. So with a real switch, the packets transmitted will be received back... and l3 mode is usually mainly usefull when using a switch. However, there is at least one nop mode where l3 submode makes sense: when the nop does not transmit. In such cases, for instace used in conjunction with a gen l3, the nop receives all packets and forward the arp requests and responses to the master for handling.

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...
