From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add new Rx offload flags `DEV_RX_OFFLOAD_RSS_HASH` These flags can be used
to enable/disable PMD writes to rte_mbuf fields `hash.rss` and also
`ol_flags:PKT_RX_RSS` and `ol_flags:PKT_RX_FDIR`.
Add new packet type set function `rte_eth_dev_set_supported_ptypes`,
allows application to inform PMDs about the packet types it is interested
in. Based on ptypes requested by application PMDs can optimize the Rx path.
For example, if a given PMD doesn't support any packet types that the
application is interested in then the application can disable[1] writes to
`mbuf.packet_type` done by the PMD and use a software ptype parser.
[1] rte_eth_dev_set_supported_ptypes(*port_id*, RTE_PTYPE_UNKNOWN,
NULL, 0);
v14 Changes:
-----------
- Remove log from drives
- Add log in rte_eth_dev_configure when certain offloads are requested to be
disabled and PMD cannot honor the request.
- Make changes to default offloads in net/sfc.(Andrew)
v13 Changes:
-----------
- Remove DEV_RX_OFFLOAD_FLOW_MARK from this patchset to allow foreward
progress will be sent as a seperate patch.
- Use set_supported function only for l2fwd and testpmd.
- Add info log in drivers which expose the DEV_RX_OFFLOAD_RSS_HASH
indicating that disabling DEV_RX_OFFLOAD_RSS_HASH is not supported.
- Few documentation changes.
v12 Changes:
-----------
- Rebase onto next-net.
v11 Changes:
-----------
- Use RTE_DIM to get array size.
- Since we are using a list of MASKs to validate ptype_mask return -EINVAL
if any unknown mask is set.
- Rebase to TOT.
v10 Changes:
-----------
- Modify ptype_mask validation in set_supported_ptypes.(Andrew)
v9 Changes:
----------
- Add ptype_mask validation in set_supported_ptypes.(Andrew)
- Make description more verbose.
v8 Changes:
----------
- Make description more verbose.
- Set RTE_PTYPE_UNKNOWN in set_ptypes array when either get ot set ptypes
is not supported by ethernet device.
v7 Changes:
----------
- Fix unused variable in net/octeontx2
v6 Changes:
----------
- Add additional checks for set supported ptypes.(Andrew)
- Clarify `rte_eth_dev_set_supported_ptypes` documentation.
- Remove DEV_RX_OFFLOAD_FLOW_MARK emulation from net/octeontx2.
v5 Changes:
----------
- Fix typos.
v4 Changes:
----------
- Set the last element in set_ptype array as RTE_PTYPE_UNKNOWN to mark the end
of array.
- Fix invalid set ptype function call in examples.
- Remove setting rte_eth_dev_set_supported_ptypes to UNKNOWN in l3fwd-power.
v3 Changes:
----------
- Add missing release notes. (Andrew)
- Re-word various descriptions.
- Fix ptype set logic.
v2 Changes:
----------
- Update release notes. (Andrew)
- Redo commit logs. (Andrew)
- Disable ptype parsing for unsupported examples. (Jerin)
- Disable RSS write only in generic mode eventdev_pipeline. (Jerin)
- Modify set_supported_ptypes function to return successfuly set mask
instead of failure.
- Dropped set_supported_ptypes to drivers by handling in library
layer, interested PMD can add it in.
