ethdev: fix strict aliasing in link up

Fix a problem introduced by a compiler upgrade (from gcc10 to gcc12.3),
which will lead the hns3 NIC can't link up. The root cause is strict
aliasing violation in rte_eth_linkstatus_set() with hns3 driver, see
[1] for more details.

This commit use union to avoid such aliasing violation. Also the
impacted components (cxgbe and qos_sched) have been adapted to the
struct change.

The DPDK framework reports the queue state, which is stored in

a queue participates in packet forwarding based on the state.
Therefore, the driver needs to modify the queue state in time
according to the actual situation.

net/cxgbe: track packets dropped by TP due to congestion

Transport Processor (TP) on the NIC delivers the incoming packets
from the wire to NIC's DMA engine to place the packets in Rx buffers.
TP sends signal towards the Multi-Port Switch (MPS) near the MAC when
the Rxqs run out of Rx buffers posted by driver. These MPS buffer drop
stats are already accounted for in imissed counters. However, if a
large number of Rxqs run out of Rx buffers simultaneously, then the
TP can start dropping packets by itself when there is heavy congestion
on the channel and hence could not inform to the MPS. So, track these
packets dropped by TP in imissed counters. Also add xstats for these
counters.

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

And instead of application setting this flag explicitly to enable jumbo

'RTE_ETHER_MTU'.

Removing this additional configuration for simplification.

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.
