Subject: [dpdk-dev] [PATCH 0/7] cxgbe: add support to offload flows via rte_flow
Date: Fri, 8 Jun 2018 23:28:10 +0530 [thread overview]
Message-ID: <cover.1528469677.git.rahul.lakkireddy@chelsio.com> (raw)
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.
Thanks,
Rahul
