The vhost library currently configures Tx offloading (PKT_TX_*) on any
packet received from a guest virtio device which asks for some offloading.
This is problematic, as Tx offloading is something that the application
must ask for: the application needs to configure devices
to support every used offloads (ip, tcp checksumming, tso..), and the
various l2/l3/l4 lengths must be set following any processing that
happened in the application itself.
On the other hand, the received packets are not marked wrt current
packet l3/l4 checksumming info.
Copy virtio rx processing to fix those offload flags with some
differences:
- accept VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP,
- ignore anything but the VIRTIO_NET_HDR_F_NEEDS_CSUM flag (to comply with
the virtio spec),
Some applications might rely on the current behavior, so it is left
untouched by default.
A new RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS flag is added to enable the
new behavior.
The vhost example has been updated for the new behavior: TSO is applied to
any packet marked LRO.

Also, the polling event modes can move to blocked call when the

The current blocked call uses the EAL interrupt API suffering a lot

Existing API supports counter action to count traffic of a single flow.
The user can share the count action among different flows using the
shared flag and the same counter ID in the count action configuration.
Recent patch [1] introduced the indirect action API.
Using this API, an action can be created as indirect, unattached to any
flow rule.
Multiple flows can then be created using the same indirect action.
The new API also supports query operation of an indirect action.
The new API is more efficient because the driver gets it's own handler
for the count action instead of managing a mapping between the user ID
to the driver handle.
Support create, query and destroy indirect action operations for flow
count action.
Application will use the indirect action query operation to query this
count action.
In the meantime the old sharing mechanism (with the sharing flag)
continues to be supported, and the user can choose the way he wants to
share the counter.
The new indirect action API is only supported in DevX, so sharing
counter action in Verbs can only be done through the old mechanism.

Add devargs to configure the platform specific getwork mode.
CN9K getwork mode by default is set to use dual workslot mode.
Add option to force single workslot mode.
Example:
--dev "0002:0e:00.0,single_ws=1"
CN10K supports multiple getwork prefetch modes, by default the
prefetch mode is set to none.
Add option to select getwork prefetch mode
Example:
--dev "0002:1e:00.0,gw_mode=1"

SSO HWGRPs i.e. queue uses DRAM & SRAM buffers to hold in-flight
events. By default the buffers are assigned to the SSO HWGRPs to
satisfy minimum HW requirements. SSO is free to assign the remaining
buffers to HWGRPs based on a preconfigured threshold.
We can control the QoS of SSO HWGRP by modifying the above mentioned
thresholds. HWGRPs that have higher importance can be assigned higher
thresholds than the rest.
Example:
--dev "0002:0e:00.0,qos=[1-50-50-50]" // [Qx-XAQ-TAQ-IAQ]
Qx -> Event queue Aka SSO GGRP.
XAQ -> DRAM In-flights.
TAQ & IAQ -> SRAM In-flights.
The values need to be expressed in terms of percentages, 0 represents
default.

The number of events for a *open system* event device is specified
as -1 as per the eventdev specification.
Since, SSO inflight events are only limited by DRAM size, the
xae_cnt devargs parameter is introduced to provide upper limit for
in-flight events.
Example:
--dev "0002:0e:00.0,xae_cnt=8192"

Add improved error handling to rte_ioat_completed_ops(). This patch adds
new parameters to the function to enable the user to track the completion
status of each individual operation in a batch. With this addition, the
function can help the user to determine firstly, how many operations may
have failed or been skipped and then secondly, which specific operations
did not complete successfully.

Rather than using a vdev with args, DPDK can scan and initialize the
devices automatically using a bus-type driver. This bus does not need to
worry about registering device drivers, rather it can initialize the
devices directly on probe.
The device instances (queues) to use are detected from /dev with the
additional info about them got from /sys.

When using a full device instance via vfio, allow the user to specify a

Since commit 7911ba0473 ("stack: enable lock-free implementation for
aarch64"), lock-free stack is supported on arm64 but this description was
missing from the doxygen for the flag.
Currently it is impossible to detect programmatically whether lock-free
implementation of rte_stack is supported. One could check whether the
header guard for lock-free stubs is defined (_RTE_STACK_LF_STUBS_H_) but
that's an unstable implementation detail. Because of that currently all
lock-free ring creations silently succeed (as long as the stack header
is 16B long) which later leads to push and pop operations being NOPs.
The observable effect is that stack_lf_autotest fails on platforms not
supporting the lock-free. Instead it should just skip the lock-free test
altogether.
This commit adds a new errno value (ENOTSUP) that may be returned by
rte_stack_create() to indicate that a given combination of flags is not
supported on a current platform.
This is detected by checking a compile-time flag in the include logic in
rte_stack_lf.h which may be used by applications to check the lock-free
support at compile time.
Use the added RTE_STACK_LF_SUPPORTED flag to disable the lock-free stack
tests at the compile time.
Perf test doesn't fail because rte_ring_create() succeeds, however
marking this test as skipped gives a better indication of what actually
was tested.
