an u8 array to hold this info.

A u64 is also needed to keep track of the DSCP values

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

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.

Application will use the indirect action query operation to query this

net/hns3: select Tx prepare based on Tx offload

Tx prepare should be called only when necessary to reduce the impact on
performance.

For partial TX offload, users need to call rte_eth_tx_prepare() to
invoke the tx_prepare callback of PMDs. In this callback, the PMDs
adjust the packet based on the offloading used by the user. (e.g. For
some PMDs, pseudo-headers need to be calculated when the TX cksum is
offloaded.)

However, for the users, they cannot grasp all the hardware and PMDs
characteristics. As a result, users cannot decide when they need to
actually call tx_prepare. Therefore, we should assume that the user
calls rte_eth_tx_prepare() when using any Tx offloading to ensure that
related functions work properly. Whether packets need to be adjusted
should be determined by PMDs. They can make judgments in the
dev_configure or queue_setup phase. When the related function is not
used, the pointer of tx_prepare should be set to NULL to reduce the
performance loss caused by invoking rte_eth_tx_repare().

In this patch, if tx_prepare is not required for the offloading used by
the users, the tx_prepare pointer will be set to NULL.

3 years agonet/bnxt: skip get statistics for stopped queues
Stephen Hemminger [Wed, 21 Apr 2021 23:09:29 +0000 (16:09 -0700)]
net/bnxt: skip get statistics for stopped queues

An application using rte_flow may define a large number of queues
but only use a small subset of them at any one time.

Since querying the status of each queue requires a request/spin/reply
with the firmware, optimize by skipping the request for queues not
running.
For those queues the statistics will be 0.

This cuts the cost of single xstats query in half and has even
bigger gain for simple stats query.
