Currently, netdev datapath offload only accelerates the flow match sequence by associating a mark per flow. This series introduces the full offload of netdev datapath flows by having the HW also perform the flow actions.
This series adds HW offload for output, drop, set MAC, set IPv4, set TCP/UDP ports and tunnel push actions using the DPDK rte_flow API. v1 Travis passed: https://travis-ci.org/elibritstein/OVS/builds/614511472 v2 Travis passed: https://travis-ci.org/elibritstein/OVS/builds/619262148 v3 Travis passed: https://travis-ci.org/elibritstein/OVS/builds/622253870 v4 Travis passed: https://travis-ci.org/elibritstein/OVS/builds/625654160 v5 Travis passed: https://travis-ci.org/elibritstein/OVS/builds/626692202 v1-v2: - fallback to mark/rss in case of any failure of action offload. - dp_layer changed to "in_hw" in case the flow is offloaded. - using netdev_ports_get instead of dp_netdev_lookup_port in stats reading. - using flow_dump_next API instead of a new API. - validity checks for last action of output and clone. - count action should be done for drop as well. - validity check for output action. - added doc in Documentation/howto/dpdk.rst. v2-v3: - removed refactoring for netdev-offload-dpdk-flow.c file. - dropped flush commits. - dbg prints rate-limited, and outside lock. - added validity check for output action - same flow_api handle for both netdevs. - added a mutex to protect possible concurrent deletion/querying of a flow. - statistics are collected using flow_get API. - added more documentation in Documentation/howto/dpdk.rst. v3-v4: - debug prints moved to netdev-offload-dpdk.c. - flow get returns full stats, not diff. - removed additional fields from offload_info and dp_netdev_flow. - read HW stats during dpif_netdev_flow_get as well as dpif_netdev_flow_dump_next. - moved actions offload framework just before support commit. - fixed memory leak in rewrite code. - dropped clone commit - will be posted in next series. v4-v5: - statistics collecting changed to populate dp_layer and offloaded attributes. dp_layer changed to "dpdk" for fully offloaded by dpdk. - display offloaded:partial for partially offloaded flows. - support filter types "dpdk" and "partially-offloaded" in dpctl/dump-flows type=X. - simplify code readability of rewrite commits.
