Currently, the defined error handling modes include:
1) NONE: it means no error handling modes are supported by this port.
2) PASSIVE: passive error handling, after the PMD detect that a reset

This release contains changes listed below.
- Fast mbuf free feature support.
- Device argument to disable the LLQ.
- Simplification of the MTU verification.
Signed-off-by: Michal Krawczyk <mk@semihalf.com>
The PMD attempts to enable the LLQ (Low Latency Queue) whenever it's
possible. The LLQ requires the user to enable the Write Combining for
the supported igb_uio/vfio-pci modules.
The vfio-pci module officially doesn't support the WC. Moreover, in some
Linux distributions, it can be built into the kernel, so any
modifications to the vfio-pci module require a full rebuild of the
kernel. This can make the configuration process much harder and for some
users, that are not interested in the great network performance for
their setups, it may be redundant. These users requested to be able to
turn off LLQ to avoid the hassle of such a setup.
It's generally not recommended to disable the LLQ, as it won't result in
the performance improvement and on the 6th generation AWS instances the
lack of LLQ can have a huge negative impact on hardware performance.
The device argument which controls the LLQ is called 'enable_llq` and by
default, it's set to 1 (which means that the LLQ is enabled). Setting
it to 0 disables the LLQ.
This commit also adds the explicit initialization of the devarg for the
'use_large_llq_hdr'. The PMD_REGISTER_PARAM_STRING() call for the ENA
was updated with all the available devargs (including
ENA_DEVARG_MISS_TXC_TO, which wasn't added previously).

Whenever Tx checksum offload is being used, the meta descriptor content
is taken into consideration. Setting DF field properly in the meta
descriptor may have huge impact on the performance both for the IPv4 and
IPv6 packets.
The requirements for the df field are as below:
* No offload used - value doesn't matter
* IPv4 - 0 or 1, depending on the DF flag in the IPv4 header
* IPv6 - 1
Setting DF to 0 causes the packet to enter the slow-path in the HW and
as a result can noticeable impact the performance.
Moreover, as 'true' may not always be mapped to 1 depending on it's
definition for the given platform/compiler, for safety DF field is being
set explicitly to 1.

Missing Tx completion reset threshold is determined dynamically, by

Now the user can configure ENA's behavior using this parameter and if

The default value is not provided by the ENA in the ena_infos_get(), as

Note that NULL check for Tx conf was removed from the function

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.

Currently, most ethdev callback API use queue ID as parameter, but Rx
and Tx queue release callback use queue object which is used by Rx and
Tx burst data plane callback.
To align with other eth device queue configuration callbacks:
- queue release callbacks are changed to use queue ID
- all drivers are adapted

Start a new release cycle with empty release notes.
The ABI version becomes 22.0.
The map files are updated to the new ABI major number (22).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.

The DPDK ENA driver does not provide multi-segment tx offload capability.
Let's add DEV_TX_OFFLOAD_MULTI_SEGS to ports offload capability by
default, and always set it in dev->data->dev_conf.txmode.offload.
This flag in not listed in doc/guides/nics/features/default.ini, so
ena.ini does not need to be updated.

Allow user to specify his own hash key and hash ctrl if the
device is supporting that. HW interprets the key in reverse byte order,
so the PMD reorders the key before passing it to the ena_com layer.
Default key is being set in random matter each time the device is being
initialized.
Moreover, make minor adjustments for reta size setting in terms
of returning error values.
RSS code was moved to ena_rss.c file to improve readability.
