839b20be0e ethdev: support metadata as flow rule criteria
As described in [1], a new rte_flow item is added to support metadata
to use as flow rule match pattern.
The metadata is an opaque item, fully controlled by the application.

The use of metadata is relevant for egress rules only.
It can be set in the flow rule using the RTE_FLOW_ITEM_META.

An additional member 'tx_metadata' is added in union with existing member
'hash' of struct 'rte_mbuf', located to avoid conflicts with existing
fields. This additional member is used to carry the metadata item.

Application should set the packet metadata in the mbuf dedicated field,
and set the PKT_TX_METADATA flag in the mbuf->ol_flags.
The NIC will use the packet metadata as match criteria for relevant
flow rules.

This patch introduces metadata item type for rte_flow RTE_FLOW_ITEM_META,
along with corresponding struct rte_flow_item_meta and ol_flag
PKT_TX_METADATA.

23ea57a2a0 ethdev: complete closing of port
After closing a port, it cannot be restarted.
So there is no reason to not free all associated resources.

The last step was done with rte_eth_dev_detach() which is deprecated.
Instead of blindly removing the associated rte_device, the driver should
check if no more port (ethdev, cryptodev, etc) is open for the device.

The last ethdev freeing which were done by rte_eth_dev_detach(),
are now done at the end of rte_eth_dev_close() if the driver supports
the flag RTE_ETH_DEV_CLOSE_REMOVE.
There will be a transition period for PMDs to enable this new flag
and migrate to the new behaviour.
When enabling RTE_ETH_DEV_CLOSE_REMOVE, the PMD must free all its
private resources for the port, in its dev_close function.
It is advised to call the dev_close function in the remove function
in order to support removing a device without closing its ports.

Some drivers does not allocate MAC addresses dynamically or separately.
In those cases, the pointer is set to NULL, in order to avoid wrongly
freeing them in rte_eth_dev_release_port().

A closed port will have the state RTE_ETH_DEV_UNUSED which is
considered as invalid by rte_eth_dev_is_valid_port().
So validity is not checked anymore for closed ports in testpmd.

662dbc322d ethdev: remove release function for secondary process
After previous changes, the function rte_eth_dev_release_port()
can be used for primary or secondary process as well.
The only difference with rte_eth_dev_release_port_secondary()
is the shared lock used in rte_eth_dev_release_port().

The function rte_eth_dev_release_port_secondary() was recently
added in 18.11 cycle.

e16adf08e5 ethdev: free all common data when releasing port
This is a clean-up of common ethdev data freeing.

deb373fb07 ethdev: add field for device data per process
Primary and secondary processes share a per-device private data. With
current design it is not possible to have data per-device per-process.
This is required for handling properly the CPP interface inside the NFP
PMD with multiprocess support.

There is also at least another PMD driver, tap, with similar
requirements for per-process device data.

5e046832f1 ethdev: rename memzones allocated for DMA
The helper rte_eth_dma_zone_reserve() is called by PMDs
when probing a new port.
It creates a new memzone with an unique name.
The name of this memzone was using the name of the driver
doing the probe.

In order to avoid assigning the driver before the end of the probing,
the driver name is removed from these memzone names.
The ethdev name (data->name) is not used because it may be too long
and may be not set at this stage of probing.

will swap source and destination MAC addresses in the outermost Ethernet
header before looping back the packet. This action can be used in
conjunction with other rewrite actions to achieve MAC layer transparent

destination MAC address is rewritten and NAT is performed.

Must be used with a valid RTE_FLOW_ITEM_TYPE_ETH flow pattern item.
Otherwise, RTE_FLOW_ERROR_TYPE_ACTION error should be returned by the
PMDs.

c2beb1d469 ethdev: add missing items/actions to flow object converter
Several pattern items and actions were never handled by rte_flow_copy()
because their descriptions were missing. rte_flow_conv() inherited this
deficiency.

This patch adds them and reorders others to match rte_flow.h. It doesn't
pose as a fix because so far no one has complained about it and
rte_flow_conv() would have to be backported as well: this function is
the only sane approach to handle VXLAN and NVGRE encap definitions.

As a matter of fact, it's the last missing piece to finally allow
testpmd users to request the creation of VXLAN/NVGRE encap/decap flow
rules without getting rejected outright.

063911ee1d ethdev: add flow API object converter
rte_flow_copy() is bound to duplicate flow rule descriptions
(attributes, pattern and list of actions, all at once), however
applications sometimes need more flexibility, for instance the ability
to duplicate only one of the underlying objects (a single pattern item
or action) or retrieve other properties such as their names.

Instead of adding dedicated functions to handle each possible use case,
this patch introduces rte_flow_conv(), which supports any number of
object conversion operations in an extensible manner.

This patch re-implements rte_flow_copy() as a wrapper to
rte_flow_conv().

a3783ebf7b ethdev: fix flow expansion matching types
Node RSS types are generally covering more RSS kind than the user is
requesting, it should accept to expand even if only a single bit is
remains after masking.  Setting the correct RSS kind for the rule
remains the driver job.

f8e9989606 remove useless constructor headers
A constructor is usually declared with RTE_INIT* macros.
As it is a static function, no need to declare before its definition.
The macro is used directly in the function definition.

4f5701f28b examples: fix RSS hash function configuration
ethdev layer introduced checks for application requested RSS hash
functions and returns error for ones unsupported by hardware

This check breaks some sample applications which blindly configures
RSS hash functions without checking underlying hardware support.

Updated examples to mask out unsupported RSS has functions during device
configuration.
Prints a log if configuration values updated by this check.

ab3ce1e0c1 ethdev: remove old offload API
In DPDK 17.11, the ethdev offloads API has changed:
	commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")
	commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
The new API is documented in the programmer's guide:
	http://doc.dpdk.org/guides/prog_guide/poll_mode_drv.html#hardware-offload

For reminder, the main concepts in the new API were:
	- All offloads are disabled by default
	- Distinction between per port and per queue offloads.

The transition bits are now removed:
	- Translation of the old API in ethdev
	- rte_eth_conf.rxmode.ignore_offload_bitfield
	- ETH_TXQ_FLAGS_IGNORE

The old API bits are now removed:
	- Rx per-port rte_eth_conf.rxmode.[bit-fields]
	- Tx per-queue rte_eth_txconf.txq_flags
	- ETH_TXQ_FLAGS_NO*

0109a56e73 ethdev: document xstats API assumption
Documents the assumption that 'xstats[i].id == i' and
key=xstats_names[i].name, value=xstats[i].value

xstats[i].id is still used for xstats _by_id() APIs.

This patch reverts some part of the commit 6d52d1d4af ("ethdev:

70815c9eca ethdev: add new offload flag to keep CRC
DEV_RX_OFFLOAD_KEEP_CRC offload flag is added. PMDs that support
keeping CRC should advertise this offload capability.

DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release
default behavior in PMDs are to keep the CRC until this flag removed

Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed:
- Setting both KEEP_CRC & CRC_STRIP is INVALID
- Setting only CRC_STRIP PMD should strip the CRC
- Setting only KEEP_CRC PMD should keep the CRC
- Not setting both PMD should keep the CRC

A helper function rte_eth_dev_is_keep_crc() has been added to be able to
change the no flag behavior with minimal changes in PMDs.

The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can
remove rte_eth_dev_is_keep_crc() checks next release, related code
commented to help the maintenance task.

And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error.
