drivers/net: advertise no support for keeping flow rules
When RTE_ETH_DEV_CAPA_FLOW_RULE_KEEP capability bit is zero, the specified behavior is the same as it had been before this bit was introduced. Explicitly reset it in all PMDs supporting rte_flow API in order to attract the attention of maintainers, who should eventually choose to advertise the new capability or not. It is already known that mlx4 and mlx5 will not support this capability.
For RTE_ETH_DEV_CAPA_FLOW_SHARED_OBJECT_KEEP similar action is not performed, because no PMD except mlx5 supports indirect actions. Any PMD that starts doing so will anyway have to consider all relevant API, including this capability.

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'.

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.

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.

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.
Note: achieved with below commands + reverted change on net/bonding + edits on crypto/virtio, compress/mlx5, regex/mlx5

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.

ethdev: remove forcing stopped state upon close
When closing a port, it is supposed to be already stopped, and marked as such with "dev_started" state zeroed by the stop API.
Resetting "dev_started" before calling the driver close operation was hiding the case of not properly stopped port being closed. The flag "dev_started" is not changed anymore in "rte_eth_dev_close()".
In case the "dev_stop" function is called from "dev_close", bypassing "rte_eth_dev_stop()" API, the "dev_started" state must be explicitly reset in the PMD in order to keep the same behaviour.

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.
