b563c14212 ethdev: remove jumbo offload flag
Removing 'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag.

Instead of drivers announce this capability, application can deduct the
capability by checking reported 'dev_info.max_mtu' or
'dev_info.max_rx_pktlen'.

And instead of application setting this flag explicitly to enable jumbo
frames, this can be deduced by driver by comparing requested 'mtu' to
'RTE_ETHER_MTU'.

Removing this additional configuration for simplification.

dd4e429c95 ethdev: move jumbo frame offload check to library
Setting MTU bigger than RTE_ETHER_MTU requires the jumbo frame support,
and application should enable the jumbo frame offload support for it.

When jumbo frame offload is not enabled by application, but MTU bigger
than RTE_ETHER_MTU is requested there are two options, either fail or
enable jumbo frame offload implicitly.

Enabling jumbo frame offload implicitly is selected by many drivers
since setting a big MTU value already implies it, and this increases
usability.

This patch moves this logic from drivers to the library, both to reduce
the duplicated code in the drivers and to make behaviour more visible.

1bb4a528c4 ethdev: fix max Rx packet length
There is a confusion on setting max Rx packet length, this patch aims to
clarify it.

'rte_eth_dev_configure()' API accepts max Rx packet size via
'uint32_t max_rx_pkt_len' field of the config struct 'struct
rte_eth_conf'.

Also 'rte_eth_dev_set_mtu()' API can be used to set the MTU, and result
stored into '(struct rte_eth_dev)->data->mtu'.

These two APIs are related but they work in a disconnected way, they
store the set values in different variables which makes hard to figure
out which one to use, also having two different method for a related
functionality is confusing for the users.

Other issues causing confusion is:
* maximum transmission unit (MTU) is payload of the Ethernet frame. And
  'max_rx_pkt_len' is the size of the Ethernet frame. Difference is
  Ethernet frame overhead, and this overhead may be different from
  device to device based on what device supports, like VLAN and QinQ.
* 'max_rx_pkt_len' is only valid when application requested jumbo frame,
  which adds additional confusion and some APIs and PMDs already
  discards this documented behavior.
* For the jumbo frame enabled case, 'max_rx_pkt_len' is an mandatory
  field, this adds configuration complexity for application.

As solution, both APIs gets MTU as parameter, and both saves the result
in same variable '(struct rte_eth_dev)->data->mtu'. For this
'max_rx_pkt_len' updated as 'mtu', and it is always valid independent
from jumbo frame.

For 'rte_eth_dev_configure()', 'dev->data->dev_conf.rxmode.mtu' is user
request and it should be used only within configure function and result
should be stored to '(struct rte_eth_dev)->data->mtu'. After that point
both application and PMD uses MTU from this variable.

When application doesn't provide an MTU during 'rte_eth_dev_configure()'
default 'RTE_ETHER_MTU' value is used.

Additional clarification done on scattered Rx configuration, in
relation to MTU and Rx buffer size.
MTU is used to configure the device for physical Rx/Tx size limitation,
Rx buffer is where to store Rx packets, many PMDs use mbuf data buffer
size as Rx buffer size.
PMDs compare MTU against Rx buffer size to decide enabling scattered Rx
or not. If scattered Rx is not supported by device, MTU bigger than Rx
buffer size should fail.

8d7d4fcdca ethdev: change input parameters for Rx queue count
Currently majority of fast-path ethdev ops take pointers to internal
queue data structures as an input parameter.
While eth_rx_queue_count() takes a pointer to rte_eth_dev and queue
index.
For future work to hide rte_eth_devices[] and friends it would be
plausible to unify parameters list of all fast-path ethdev ops.
This patch changes eth_rx_queue_count() to accept pointer to internal
queue data as input parameter.
While this change is transparent to user, it still counts as an ABI change,
as eth_rx_queue_count_t is used by ethdev public inline function
rte_eth_rx_queue_count().

851f03e1ea net/nfp: cancel delayed LSC work in port close
The link state change interrupt handler of the NFP PMD will delay the
actual LSC work for a short period to ensure the link is stable. If the
link of the port changes state and the port is closed immediately after
the link event then a segmentation fault will occur. This happens
because the delayed LSC work eventually triggers and this logic will try
to access private port data that had been released when the port was
closed.

96289f2b80 net/nfp: fix minimum descriptor sizes
The NFP4000/6000 supports a minimum of 256 Tx/Rx descriptors and not 64.
Before this patch when a DPDK application configured < 256 Tx
descriptors the hardware read/write pointers would be unmasked and not
wrapped at the expected size of the ring. The PMD logic to determine the
amount of free space in the Tx ring is incompatible with the unmasked
hwqueue pointers and this will result in the PMD not updating the
read pointer at all.The knock-on effect is that under high load the
PMD will potentially re-use a Tx descriptor before the hw has had a
chance to process that particular descriptor. This issue can manifest as
a DMA error when the hardware tries to perform a DMA with info from a
partially populated descriptor.

0b3c74b9f7 net/nfp: fix multi-process PF probing
This patch creates a new function for handling PF probing of a secondary
process. A CPP handle is obtained for the CPP bridge service and the
service itself is also registered during secondary process
initialization. DPDK services aren't shared between processes so it is
not enough to only have the primary register the service if it is also
needed in a secondary process. This implies that both the primary and
secondary will have their own copy of the bridge service.

82caefd8d7 net/nfp: improve PF probing logic
When using rte_eth_dev_pci_generic_probe() during probing a
rte_eth_dev will be created with the name field corresponding to the PCI
address of the device. NFP4000/6000 devices only have a single PF (but
potentially multiple physical ports). This means that in a simple two
port example the rte_eth_devices[] array will be populated with two
devices: 0000:02:00.0 and 0000:02:00.0_port1. This is inconsistent and
not ideal. It will also cause issues when a secondary process tries to
attach to these ports.

This patch removes the use of rte_eth_dev_pci_generic_probe() and
allocates eth_dev's for each physical port during PF initialization,
giving them more consistent names.

eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

5e15e799d6 net/nfp: create separate entity for PF device
Before this change memory for the private data of all physical ports
where allocated with single rte_zmalloc() call. Specific port private
data was accessed by means of an offset into this memory. This scheme is
problematic when attempting to free only one port's private data at a
time.

To address this, a new entity is created called struct nfp_pf_dev. This
struct represents the PF device. It has a number of PF specific members.
Notably it has a pointer of type rte_eth_dev that points to the eth_dev
associated with the first physical port of the device. It also has an
array of nfp_net_hw's containing pointers to all the physical ports
under the PF.

Memory is first allocated for the PF and PF specific initialization is
attempted. Next, all the physical ports under the PF is iterated and
memory is allocated separately for the private data of each port. Port 0
is skipped during this phase because memory has already been allocated
and an eth_dev already exits for the 0th port.

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.

3041049375 drivers/net: check process type in close operation
The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
Most of the time, there is no process-private resource,
so the close operation is just forbidden in a secondary process.

After adding proper check in the port close functions,
some redundant checks in the device remove functions are dropped.

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;

50ce3e7aec ethdev: fix VLAN offloads set if no relative capabilities
Currently, there is a potential problem that calling the API function
rte_eth_dev_set_vlan_offload to start VLAN hardware offloads which the
driver does not support. If the PMD driver does not support certain VLAN
hardware offloads and does not check for it, the hardware setting will
not change, but the VLAN offloads in dev->data->dev_conf.rxmode.offloads
will be turned on.

It is supposed to check the hardware capabilities to decide whether the
relative callback needs to be called just like the behavior in the API
function named rte_eth_dev_configure. And it is also needed to cleanup
duplicated checks which are done in some PMDs. Also, note that it is
behaviour change for some PMDs which simply ignore (with error/warning
log message) unsupported VLAN offloads, but now it will fail.
