2018-01-17plugins: odp: Add support for buffer recyclingMichal Mazur1-13/+53
Buffers with VLIB_BUFFER_RECYCLE flag set should not be freed. They are replicated on send and sent back to vlib for processing. Change-Id: If381884fa7c898253f35dc3a39feeb4eb1529286 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2017-12-18More optimizations for Tx and Rx loopsMichal Mazur1-49/+88
1) Parse multiple output packets in loop. 2) Remove checking for error flags, they are never set because ODP parser is disabled. 3) Do not call vlib_buffer_advance if not necessary. 4) Remove lock in TX path. Queues are synchronized by ODP. 5) Optimize detection of packet type. 6) Create a wrapper for call to odp_packet_user_area.

2017-12-14Read ODP configuration from VPP startup configMichal Mazur1-8/+8
1) Allow to setup size of allocated memory, number of packets in the pool, number of packets in transmit burst and delay in scheduler mode from VPP startup file. More details are in template: src/vpp/conf/startup.conf 2) Separate Rx mode from Tx mode. Traffic Manager is not supported. 3) Devices defined in VPP startup are automatically created at start.

2017-12-14Add support for multiple Rx and Tx queuesMichal Mazur1-9/+22
1) Incoming packets can be spread across multiple worker threads based on IP and TCP/UDP headers. 2) Multiple output queues are used in Burst mode if supported by hardware (checked in interface capabilities) 3) Synchronization of output traffic can be disabled due to multiple Tx queues - one for each thread.

2017-12-14Optimize Rx and Tx pathsMichal Mazur1-0/+10
1) Handle multiple ODP packets at once in receive loop 2) Wait to collect as many RX buffers as possible in single vector 3) Add prefetch of received and transmitted buffers 4) Disable parser, classifier and synchronization of RX queues Synchronization of Tx queues can also be disabled if 2 ports used.

2017-12-14Move odp_packet_main structure to shared memory.Michal Mazur1-4/+4
This structure contains data shared among multiple threads and must be globally accessible. Change-Id: Ibde8222e9ed3f61561f7902750a1716da5c0bd81 Signed-off-by: Michal Mazur <mkm@semihalf.com>
