627b3c5a39 net/iavf: fix shared data in multi-process
The shared pointer is initialized to a static local array defined in the
primary process and it shall not be accessed in the secondary process.

This patch copies the local data to shared data, to avoid data access
violation.

ede6356582 drivers/net: fix removing jumbo offload flag
After DEV_RX_OFFLOAD_JUMBO_FRAME flag removed, drivers give jumbo frame

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.

cd3b124955 net/iavf: enable interrupt polling
For VF hosted by Intel 700 series NICs, internal Rx interrupt and adminq
interrupt share the same source, that cause a lot CPU cycles be wasted on
interrupt handler on Rx path.

The patch disable PCI interrupt and remove the interrupt handler, replace
it with a low frequency(50ms) interrupt polling daemon which is
implemented by registering an alarm callback periodically.

The virtual channel capability bit VIRTCHNL_VF_OFFLOAD_WB_ON_ITR can be
used to negotiate if iavf PMD needs to enable background alarm or not, so
ideally this change will not impact the case hosted by Intel 800 series
NICS.

This patch implements the same logic with an early i40e commit:

The len variable, used in the computation of max_pkt_len could
overflow, if used to store the result of the following computation:

rxq->rx_buf_len * IAVF_MAX_CHAINED_RX_BUFFERS

Since, we could define the mbuf size to have a large value (i.e 13312),
and IAVF_MAX_CHAINED_RX_BUFFERS is defined as 5, the computation
mentioned above could potentially result in a value which might be
bigger than MAX_USHORT.

The result will be that Jumbo Frames will not work properly

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.

The i40evf PMD will be deprecated, iavf will be the only VF driver for
Intel 700 serial (i40e) NIC family.

To reach this, there will be 2 steps:

Step 1: iavf will be the default VF driver, while i40evf still can be
selected by devarg: "driver=i40evf".
This is covered by this patch, which include:
1) add all 700 serial NIC VF device ID into iavf PMD
2) skip probe if devargs contain "driver=i40evf" in iavf
3) continue probe if devargs contain "driver=i40evf" in i40evf

Step 2: i40evf and related devarg are removed, this will happen at DPDK
21.11

Between step 1 and step 2, no new feature will be added into i40evf
except bug fix.

7abd466423 net/iavf: fix jumbo frame flag condition
The jumbo frame uses the 'RTE_ETHER_MAX_LEN' as boundary condition,
but the Ether overhead is larger than 18 when it supports dual VLAN tags.
That will cause the jumbo flag rx offload is wrong when MTU size is
'RTE_ETHER_MTU'.

This fix will change the boundary condition with 'RTE_ETHER_MTU' and
overhead, that perhaps impacts the cases of the jumbo frame related.

1c301e8c3c net/iavf: support new VLAN capabilities
The new VLAN virtchnl opcodes introduce new capabilities like VLAN
filtering, stripping and insertion.

The AVF needs to query the VLAN capabilities based on current device
configuration firstly.

AVF is able to configure inner VLAN filter when port VLAN is enabled
base on negotiation; and AVF is able to configure outer VLAN (0x8100)
if port VLAN is disabled to be compatible with legacy mode.

When port VLAN is updated by DCF, the AVF needs to reset to query the
new VLAN capabilities.

Enable metadata extraction for flexible descriptors in AVF, that would
allow network function directly get metadata without additional parsing
which would reduce the CPU cost for VFs. The enabling metadata
extractions involve the metadata of VLAN/IPv4/IPv6/IPv6-FLOW/TCP/MPLS
flexible descriptors, and the VF could negotiate the capability of
the flexible descriptor with PF and correspondingly configure the
specific offload at receiving queues.

ead06572bd net/iavf: fix performance with writeback policy
The iavf driver was trying to use writeback on ITR, but was
never setting an ITR, so it didn't work. This caused performance
to be limited due to too much PCIe traffic and partial writes
during most benchmarking workloads.
Set the ITR during queue setup, which can be checked at runtime
by reading register 0x2800. Setting the value to 2us allows
for generally good streaming packet performance while keeping
latency down.
