This series add basic support to offload flows to Chelsio T5/T6 NICs via rte_flow API. Chelsio NICs can support wildcard (maskfull) filters and exact (maskless) filters. Filters can be created in two regions available on Chelsio NICs. The smaller LE-TCAM region can support both maskfull and maskless filters; whereas, the larger HASH region can support only maskless filters. This series adds support for LE-TCAM region. Support for HASH region will be added in subsequent series.
This series adds support for: <match item>: IPv4, IPv6, TCP, and UDP. <action>: Drop, Queue, and Count. Support for more match items and actions will be added in subsequent series. Patch 1 queries firmware for available filtering resources in the underlying device and adds table to manage these resources. Patch 2 introduces rte_flow skeleton and implementes validate operation. Patch 3 exports control queue needed for communicating filter create/delete requests with firmware. Patch 4 adds firmware API to create filter work requests for creating/deleting filters and implements flow create operation. Patch 5 adds flow destroy operation. Patch 6 adds flow query operation to get filter hit and byte counts. Patch 7 adds flow flush operation to delete all filters under specified port.
