External topology devices (e.g. PHYs) connected to 100G or to SoC that

the firmware is usually loaded from NVM connected to the topology
device.
The topology device NVM images can be updated using SW tools but
such solution poses a security risk if there is no validation of
the integrity of an image before programming it to the device NVM.
In order to prevent security risk, the topology device NVM image might
be included as part of 100G NVM image. When the topology device
NVM image is present in the 100G NVM image, it is authenticated
and might be loaded to the topology device at startup or on command

The base code support to build configuration TLVs
in DSCP mode has not been implemented before, so
the functions to do so and the flow control to determine
if we are in VLAN or DSCP mode need to be added.
The current value for maximum number of DCB APPs
(ICE_DCBX_MAX_APPS) is not sufficient when supporting
DSCP mode. Each DSCP->TC mapping will come in as a
single APP value. So, there can be up to 64 APPs for
DSCP mapping.
Need to keep track of the current DSCP to TC mapping
so that TLVs can be built up to send to the FW. Add
an u8 array to hold this info.
A u64 is also needed to keep track of the DSCP values
that have had an APP submitted to map its value to a
TC. Since it would be unwise to allow an APP to be
overwritten by subsequent APPs, reject mappings for a
DSCP value that already has a user mapped value. This
will allow us to easily track which DSCP values have
been mapped, and when the last one has been deleted.

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.

The driver support 2 mechanisms in order to support AGE action:

the driver polls the counter values efficiently to detect flow timeout.
2. Aging by ASO flow hit bit - HW ASO flow-hit bit is allocated for the
flow, the driver polls the bit efficiently to detect flow timeout.
ASO bit is only single bit resource while counter is 16 bytes, hence, it
is better to use ASO instead of counter for aging.
When a non-shared COUNT action is also configured to the flow, the
driver can use the same counter also for AGE action and no need to
create more ASO action for it.
The current code always uses ASO when it is supported in the device,
change it to reuse the non-shared counter if it exists in the flow.

Existing API supports counter action to count traffic of a single flow.
The user can share the count action among different flows using the

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.

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.

But the time which gets from gettimeofday() API isn't monotonically
increasing. The process may fail if the system time is changed.
We use the following scheme to fix it:
1. Add hns3_clock_gettime() API which will get the monotonically
increasing time.
2. Add hns3_clock_calctime_ms() API which will get the milliseconds of
the monotonically increasing time.
3. Add hns3_clock_calctime_ms() API which will calc the milliseconds of
a given time.
