cb95feefdd net/mlx5: support sub-function representor
This patch adds support for SF representor. Similar to VF representor,
switch port name of SF representor in phys_port_name sysfs key is
"pf<x>sf<y>".

Device representor argument is "representors=sf[list]", list member
could be mix of instance and range. Example:
  representors=sf[0,2,4,8-12,-1]

To probe VF representor and SF representor, need to separate into 2
devices:
  -a <BDF>,representor=vf[list] -a <BDF>,representor=sf[list]

59df97f1a8 common/mlx5: support sub-function representor parsing
This patch supports representor name parsing for SF.
In sysfs, representor name stored under "phys_port_name" sysfs key,
similar to VF representor, switch port name of SF representor is
"pf<x>sf<y>".

For netlink message, net SF type is supported.

Examples:

pf0sf1
pf0sf[0-3]

e0ae50c687 build: remove redundant _GNU_SOURCE definitions
The feature macro _GNU_SOURCE is defined globally,
but there was some remaining useless settings.

d61381ad46 net/mlx5: support timestamp format
This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.

The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.

e6988afdc7 net/mlx5: fix imissed statistics
The imissed port statistic counts packets that were dropped by the
device Rx queues.

In mlx5, the imissed counter summarizes 2 counters:
	- packets dropped by the SW queue handling counted by SW.
	- packets dropped by the HW queues due to "out of buffer" events
	  detected when no SW buffer is available for the incoming
	  packets.

There is HW counter object that should be created per device, and all
the Rx queues should be assigned to this counter in configuration time.

This part was missed when the Rx queues were created by DevX what
remained the "out of buffer" counter clean forever in this case.

Add 2 options to assign the DevX Rx queues to queue counter:
	- Create queue counter per device by DevX and assign all the
	  queues to it.
	- Query the kernel counter and assign all the queues to it.

Use the first option by default and if it is failed, fallback to the
second option.

fdc44cdc78 net/mlx5: fix miniCQE configuration for Verbs
Verbs cannot be used to configure newly introduced miniCQE formats for
Flow Tag and L3/L4 Header compression. Support for these formats has
been added to the DevX configuration only. And the RX queue descriptor
has been updated with the CQE compression format information only as
well. But the datapath relies on this info no matter which method is
used for Rx queues configuration. Set proper CQE compression format
information in the Verbs configuration to fix the miniCQE parsing logic.

2b36c30b8c net/mlx5: fix port attach in secondary process
Currently, the secondary process port UAR register mapping used by Tx
queue is done during port initializing.

Unluckily, in port hot-plug case, the secondary process was requested
to initialize the port when primary process did not complete the
device configuration and the port Tx queue number is not configured
yet. Hence, the secondary process gets the zero Tx queue number during
probing, causing the UAR registers not be mapped in the correct
fashion.

This commit checks the configured number of Tx queues in secondary
process when the port start is requested. In case the Tx queue
number mismatch found the UAR mapping is reinitialized accordingly.

f5b0aed2df net/mlx5: optimize hash list entry memory
Currently, the hash list saves the hash key in the hash entry. And the
key is mostly used to get the bucket index only.

Save the entire 64 bits key to the entry will not be a good option if
the key is only used to get the bucket index. Since 64 bits costs more
memory for the entry, mostly the signature data in the key only uses
32 bits. And in the unregister function, the key in the entry causes
extra bucket index calculation.

This commit saves the bucket index to the entry instead of the hash key.
For the hash list like table, tag and mreg_copy which save the signature
data in the key, the signature data is moved to the resource data struct
itself.

The sample and mirror action objects are maintained on the list

The actions in the NIC steering domains might contain the references
to the sub-flow action objects created over the given port. The action
deletion might happen in the context of the different port and on the
deletion of referenced objects the incorrect port might be specified.
To avoid this we should save the port on what the sub-flow actions
were created and then use this saved port for sub-flow action release.

This commit saves the create device in the sample and mirror actions
struct to avoid using the incorrect port device in releasing.

The Tx queue stop API doesn't call the PMD callback when the state of
the queue is stopped.
The drivers should update the state to be stopped when the queue stop
callback is done successfully or when the port is stopped.
The drivers should update the state to be started when the queue start
callback is done successfully or when the port is started.

The driver wrongly didn't update the state as started when the port
start callback was done which kept the state as stopped.
Following call to a queue stop API was not completed by ethdev layer
because the state is already stopped.

Move the state update from the Tx queue setup to the port start
callback.

e82ddd28e3 common/mlx5: split PCI relaxed ordering for read and write
The current DevX implementation of the relaxed ordering feature is
enabling relaxed ordering usage only if both relaxed ordering read AND
write are supported.  In that case both relaxed ordering read and write
are activated.

This commit will optimize the usage of relaxed ordering by enabling it
when the read OR write features are supported.  Each relaxed ordering
type will be activated according to its own capability bit.

This will align the DevX flow with the verbs implementation of
ibv_reg_mr when using the flag IBV_ACCESS_RELAXED_ORDERING

f935ed4b64 net/mlx5: support flow hit action for aging
A new ASO (Advanced Steering Operation) feature was added in the last
mlx5 adapters to support flow hit detection.

Using this new steering action, the driver can detect flow traffic hit
and to reset this indication any time.

The ASO age action cannot support flows in table 0.

Add support for flow aging action in rte_flow using this new feature.

The counter aging mode will be taken only when the ASO feature is not
supported for the user flow groups.

02109eaeac net/mlx5: support getting hairpin peer ports
In real-life business, one device could be attached and detached
dynamically. The hairpin configuration of this port to/from all the
other ports should be enabled and disabled accordingly.

The RTE ethdev lib and PMD should provide this ability to get the
peer ports list in case that the application doesn't save it. It is
recommended that the size of the array to save the port IDs is as
large as the "RTE_MAX_ETHPORTS" to have the maximal capacity.

The order of the peer port IDs may be different from that during
hairpin queues set in the initialization stage. The peer port ID
could be the same as the current device port ID when the hairpin
peer ports contain itself - the single port hairpin.

The application should check the ports' status and decide if the
peer port should be bound / unbound when starting / stopping the
current device.

In order to support hairpin between two ports, mlx5 PMD needs to
implement the functions and provide them as the function pointers.

The bind and unbind functions are executed per port pairs. All the
hairpin queues between the two ports should have the same attributes
during queues setup. Different configurations among queue pairs from
the same ports are not supported. It is allowed that two ports only
have one direction hairpin.

In order to set up the connection between two queues, peer Rx queue
HW information must be fetched via the internal RTE API and the queue
information could be used to modify the SQ object. Then the RQ object
will be modified with the Tx queue HW information. The reverse
operation is not supported right now.

When disconnecting the queues pair, SQ and RQ object should be reset
without any peer HW information. The unbinding operation will try to
disconnect all Tx queues from the port from the Rx queues of the peer
port.

Tx explicit mode attribute will be saved and used when creating a
hairpin flow.

In this case, the DevX object can be saved to the generic counter struct
union with entry memory when counter is allocated and union with bytes
when counter is free.
And pool type is also not needed as non-fallback mode only has generic

994829e695 net/mlx5: remove single counter container
A flow counter which was allocated by a batch API couldn't be assigned
to a flow in the root table (group 0) in old rdma-core version.
Hence, a root table flow counter required PMD mechanism to manage
counters which were allocated singly.

Currently, the batch counters have already been supported in root table
includes a new rdma-core version with MLX5_FLOW_ACTION_COUNTER_OFFSET
enum and with a kernel driver includes
MLX5_IB_ATTR_CREATE_FLOW_ARR_COUNTERS_DEVX_OFFSET enum.

When the PMD uses rdma-core API to assign a batch counter to a root
table flow using invalid counter offset, it should get an error only
if the batch counter assignment for root table is supported.
Using this trial in the initialization time can help to detect the
support.

Using the above trial, if the support is valid, remove the management of
single counter container in the fast counter mechanism. Otherwise, move
the counter mechanism to fallback mode.

f30e69b41f ethdev: add device flag to bypass auto-filled queue xstats
Queue stats are stored in 'struct rte_eth_stats' as array and array size
is defined by 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag.

As a result of technical board discussion, decided to remove the queue
statistics from 'struct rte_eth_stats' in the long term.

Instead PMDs should represent the queue statistics via xstats, this
gives more flexibility on the number of the queues supported.

Currently queue stats in the xstats are filled by ethdev layer, using
some basic stats, when queue stats removed from basic stats the
responsibility to fill the relevant xstats will be pushed to the PMDs.

During the switch period, temporary 'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS'
device flag is created. Initially all PMDs using xstats set this flag.
The PMDs implemented queue stats in the xstats should clear the flag.

When all PMDs switch to the xstats for the queue stats, queue stats
related fields from 'struct rte_eth_stats' will be removed, as well as
'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS' flag.
Later 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag also can be
removed.

fbd1913561 ethdev: remove old close behaviour
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE is removed.
It was introduced in DPDK 18.11 in order to give time for PMDs to migrate.

The old behaviour was to free only queues when closing a port.
The new behaviour is calling rte_eth_dev_release_port() which does
three more tasks:
	- trigger event callback
	- reset state and few pointers
	- free all generic port resources

The private port resources must be released in the .dev_close callback.

The .remove callback should:
	- call .dev_close callback
	- call rte_eth_dev_release_port()
	- free multi-port device shared resources

Despite waiting two years, some drivers have not migrated,
so they may hit issues with the incompatible new behaviour.
After sending emails, adding logs, and announcing the deprecation,
the only last solution is to declare these drivers as unmaintained:
	ionic, liquidio, nfp
Below is a summary of what to implement in those drivers.

* The freeing of private port resources must be moved
from the ".remove(device)" function to the ".dev_close(port)" function.

* If a generic resource (.mac_addrs or .hash_mac_addrs) cannot be freed,
it must be set to NULL in ".dev_close" function to protect from
subsequent rte_eth_dev_release_port() freeing.

* Note 1:
The generic resources are freed in rte_eth_dev_release_port(),
after ".dev_close" is called in rte_eth_dev_close(), but not when
calling ".dev_close" directly from the ".remove" PMD function.
That's why rte_eth_dev_release_port() must still be called explicitly
from ".remove(device)" after calling the ".dev_close" PMD function.

* Note 2:
If a device can have multiple ports, the common resources must be freed
only in the ".remove(device)" function.

* Note 3:
The port is supposed to be in a stopped state when it is closed.
If it is not the case, it is free to the PMD implementation
how to react when trying to close a non-stopped port:
either try to stop it automatically or just return an error.

c21e5facf7 net/mlx5: use bond index for netdev operations
In case of bonding, device ifindex was detected as the PF ifindex, so
any operation using ifindex applied to PF instead of the bond device.
These operations includes MTU get/set, up/down and mac address
manipulation, etc.

This patch detects bond interface ifindex and name for PF that join a
bond interface, uses it by default for netdev operations.

7aa9892f79 net/mlx5: fix Rx objects creator selection
There are 2 creators for Rx objects, DevX and Verbs.
There are supported DR versions when a DevX destination TIR flow action
creation cannot be supported, using this versions the TIR object should
be created by Verbs, what forces all the Rx objects to be created by
Verbs.

The selection of the Rx objects creator, wrongly, didn't take into
account the destination TIR action support what caused a failure in the
Rx flows creation.

Select Verbs creator when destination TIR action creation is not
supported by the DR version.

5723fbed4f ethdev: remove underscore prefix from internal API
'_rte_eth_dev_callback_process()' & '_rte_eth_dev_reset()' internal APIs
has unconventional underscore ('_') prefix.
Although this is not documented most probably this is to mark them as
internal. Since we have '__rte_internal' flag to mark this, removing '_'
from API names.

For '_rte_eth_dev_reset()', there is already a public API named
'rte_eth_dev_reset()', so renaming '_rte_eth_dev_reset()' to
'rte_eth_dev_internal_reset'.

cbfc6111b5 ethdev: move inline device operations
This patch is a preparation to hide the 'struct eth_dev_ops' from
applications by moving some device operations from 'struct eth_dev_ops'
to 'struct rte_eth_dev'.

Mentioned ethdev APIs are in the data path and implemented as inline
because of performance reasons.

Exposing 'struct eth_dev_ops' to applications is bad because it is a
contract between ethdev and PMDs, not really needs to be known by
applications, also changes in the struct causing ABI breakages which
shouldn't.

To be able to both keep APIs inline and hide the 'struct eth_dev_ops',
moving device operations used in ethdev inline APIs to 'struct
rte_eth_dev' to the same level with Rx/Tx burst functions.

The list of dev_ops moved:
eth_rx_queue_count_t       rx_queue_count;
eth_rx_descriptor_done_t   rx_descriptor_done;
eth_rx_descriptor_status_t rx_descriptor_status;
eth_tx_descriptor_status_t tx_descriptor_status;

When debugging performance of a DPDK application the user may
need to view the different statistics of DPDK (for example out_of_buffer)
This can be enabled by using testpmd command 'show port xstats

The current implementation assumes legacy mode in which the counters
are at <ibdev_path>/<port_id>/hw_counters/<file_name>.
In switchdev mode the counters file is located right after the device
name, hence resides at <ibdev_path>/hw_counters.

The fix tries to open the path in the second location after a failure
to open the file from the first location.

161d103b23 net/mlx5: add queue start and stop
The mlx5 PMD did not support queue_start and queue_stop eth_dev API
routines, queue could not be suspended and resumed during device
operation.

There is the use case when this feature is crucial for applications:

- there is the secondary process handling the queue
- secondary process crashed/aborted
- some mbufs were allocated or used by secondary application
- some mbufs were allocated by Rx queues to receive packets
- some mbufs were placed to send queue
- queue goes to undefined state

In this case there was no reliable way to recovery queue handling
by restarted secondary process but reset queue to initial state
freeing all involved resources, including buffers involved in queue
operations, reset the mbuf pools, and then reinitialize queue
to working state:

- reset mbuf pool, allocate all mbuf to initialize pool into
  safe state after the crush and allow safe mbuf free calls
- stop queue, free all potentially involved mbufs
- reset mbuf pool again
- start queue, reallocate mbufs needed

This patch introduces the queue start/stop feature with some
limitations:

- hairpin queues are not supported
- it is application responsibility to synchronize start/stop
  with datapath routines, rx/tx_burst must be suspended during
  the queue_start/queue_stop calls
- it is application responsibility to track queue usage and
  provide coordinated queue_start/queue_stop calls from
  secondary and primary processes.
- Rx queues with vectorized Rx routine and engaged CQE
  compression are not supported by this patch currently

There are some limitations on some NICs (at least on ConnectX-6 Dx
and BlueField 2) with supporting FCS (frame checksum) scattering for
the tunnel decapsulated packets.

For the case only one of the features can be supported in the same time,
and the new devarg "decap_en" is introduced to provide the choice to the
users.

If FCS scattering feature is not supposed to be engaged by application,
this new devarg should be specified as "decap_en=0", forcing the FCS
feature enable and rejecting tunnel decap actions in the rte_flow engine.
If FCS scatter is not needed and application supposes to use tunnel
decapsulation in rte_flow, the devarg can be omitted or set to non-zero
value (this is default settings).

5522da6b20 net/mlx5: add option to allocate memory from system
Currently, for MLX5 PMD, once millions of flows created, the memory
consumption of the flows are also very huge. For the system with limited
memory, it means the system need to reserve most of the memory as huge
page memory to serve the flows in advance. And other normal applications
will have no chance to use this reserved memory any more. While most of
the time, the system will not have lots of flows, the  reserved huge
page memory becomes a bit waste of memory at most of the time.

By the new sys_mem_en devarg, once set it to be true, it allows the PMD
allocate the memory from system by default with the new add mlx5 memory
management functions. Only once the MLX5_MEM_RTE flag is set, the memory
will be allocate from rte, otherwise, it allocates memory from system.

So in this case, the system with limited memory no need to reserve most
of the memory for hugepage. Only some needed memory for datapath objects
will be enough to allocated with explicitly flag. Other memory will be
allocated from system. For system with enough memory, no need to care
about the devarg, the memory will always be from rte hugepage.

One restriction is that for DPDK application with multiple PCI devices,
if the sys_mem_en devargs are different between the devices, the
sys_mem_en only gets the value from the first device devargs, and print
out a message to warn that.

writes, protected by lock. Due to possibility to share the same
UAR between sibling devices the locks must be moved to shared
context.

8f848f32fc net/mlx5: introduce send scheduling devargs
This patch introduces the new devargs:

tx_pp - enables accurate packet send scheduling on mbuf timestamps
  in the PMD. On the device start if "rte_dynflag_timestamp"
  dynamic flag is registered and this devarg non-zero value is
  specified, the driver initializes all necessary internal
  infrastructure to provide packet scheduling. The parameter
  value specifies scheduling granularity in nanoseconds.

tx_skew - the parameter adjusts the send packet scheduling on
  timestamps and represents the average delay between beginning
  of the transmitting descriptor processing by the hardware and
  appearance of actual packet data on the wire. The value should
  be provided in nanoseconds and is valid only if tx_pp parameter
  is specified. The default value is zero.

b293fbf967 net/mlx5: add OS specific flow actions operations
This patch introduces the OS specific functions, for flow actions
create and destroy operations.

In existing implementation, the functions to create flow actions
return a pointer to the created action object.

The new OS specific functions to create flow actions return 0 on
success, and (-1) on failure.
On success, a pointer to the created action object is returned
using an additional parameter.
On failure errno is set.

e4ed8de39b net/mlx5: add OS specific flow type selection
In current implementation the flow type (DV/Verbs) is selected
using dedicated function flow_get_drv_type().

This patch adds OS specific function mlx5_flow_os_get_type(), to
allow OS specific flow type selection.
The new function is called by flow_get_drv_type(), and if it returns a
valid value (DV/Verbs) no more logic is required.
Otherwise the existing logic is executed.

17ad3af9f4 net/mlx5: add OS specific flow related utilities
This patch introduces the first OS specific utility functions,
for use by flow engine in different OS implementation.

The first utility functions are:
bool mlx5_flow_os_item_supported(item)
bool mlx5_flow_os_action_supported(action)

They are implemented to check OS specific support for different
item types and action types.

New header file is added:
drivers/net/mlx5/linux/mlx5_flow_os.h

This file contains the utility functions mentioned above for Linux OS.
At this stage they are implemented as static inline, for efficiency,
and always return true.

36dabcea78 net/mlx5: use anonymous Direct Verbs allocator argument
The mlx5_dev_spawn function defines an struct mlx5dv_ctx_allocators type
variable several hundred rows after it starts, with the only use it
being passed as a parameter to the mlx5_glue->dv_set_context_attr
function.
However, according to DPDK Coding Style Guidelines, variables should be
declared at the start of a block of code rather than in the middle.
Therefore, to improve the Coding Style, the variable is passed directly
to the function without declaring it before.

420bbdae89 net/mlx5: fix host physical function representor naming
The new kernel adds the names like "pf0" for Host PCI physical
function representor on Bluefield SmartNIC hosts. This patch
provides correct HPF representor recognition over the kernel
versions 5.7 and laters.

The following port naming formats are supported:

  - missing physical port name (no sysfs/netlink key) at all,
    master is assumed

  - decimal digits (for example "12"), representor is
    assumed, the value is the index of attached VF

  - "p" followed by decimal digits, for example "p2", master
    is assumed

  - "pf" followed by PF index, for example "pf0", Host PF
     representor is assumed on SmartNIC systems.

  - "pf" followed by PF index concatenated with "vf" followed by
     VF index, for example "pf0vf1", representor is assumed.
     If index of VF is "-1" it is a special case of Host PF
     representor, this representor must be indexed in devargs
     as 65535, for example representor=[0-3,65535] will
     allow representors for VF0, VF1, VF2, VF3 and for host PF.

391b8bcc81 common/mlx5: move some getter functions from net driver
Getter functions such as: 'mlx5_os_get_ctx_device_name',
'mlx5_os_get_ctx_device_path', 'mlx5_os_get_dev_device_name',
'mlx5_os_get_umem_id' are implemented under net directory. To enable
additional devices (e.g. regex, vdpa) to access these getter functions
they are moved under common directory.

As part of this commit string sizes DEV_SYSFS_NAME_MAX and
DEV_SYSFS_PATH_MAX are increased by 1 to make sure that the destination
string size in strncpy() function is bigger than the source string size.
This update will avoid GCC version 8 error -Werror=stringop-truncation.

aec086c9f1 common/mlx5: share kernel interface name getter
Some configuration of the mlx5 port are done by the kernel net device
associated to the IB device represents the PCI device.

The DPDK mlx5 driver uses Linux system calls, for example ioctl, in
order to configure per port configurations requested by the DPDK user.

One of the basic knowledges required to access the correct kernel net
device is its name.

Move function to get interface name from IB device path to the common
library.
