I agree with Mr. Thomas Monjalon. Any optimization in DPDK structure should
be made open.
Previously, link status interrupt in i40e is achieved by checking
LINK_STAT_CHANGE_MASK in PFINT_ICR0 register which is provided only
for diagnostic use. Instead, drivers need to get the link status
change notification by using LSE (Link Status Event).
This patch enables LSE and calls LSC callback
Originally, using DPDK as host driver, when VF bonded device
uses I40E_VIRTCHNL_OP_GET_LINK_STAT to query PF the link status,
VF will wait for the interrupt from PF to get this link status.
PF uses interrupt which already exists to communication with VF.
These two kinds of interrupt will be confusi

This patch adds File Descriptor(FD) port type (e.g. TAP port) to the
packet framework library that allows interface with the kernel network
stack. The FD port APIs are defined that allow port creation, writing
and reading packet from the kernel interface.
Signed-off-by: Jasvinder Singh
Acked-by:
The TAP port support is added to ip_pipeline app. To parse
configuration file with TAP port entries, parsing function is implemented.
The TAP ports configuration check and initialization routines have been
included in application code.
Signed-off-by: Jasvinder Singh

To illustrate the TAP port usage, the sample configuration file with
passthrough pipeline connected to TAP interface is added.

The commit that disabled tso for small packets was broken during the
rebase. The problem is the IP checksum is not calculated in software if:
- TX IP checksum is disabled
- TSO is enabled
- the current packet is smaller than tso segment size

Applied, thanks
This patchset, targetted for 16.11, introduces the support of rx and tx
offload in virtio pmd. To achieve this, some new mbuf flags must be
introduced, as discussed in [1].
It applies on master + a patch fixing the testpmd csum engine:
http://dpdk.org/dev/patchwork/patch/16538/
The new mbuf chec
Move all code related to device initialization in a new function
virtio_init_device().
This commit brings no functional change, it prepares the next commits
that will add the offload support. For that, it will be needed to
reinitialize the device from ethdev->configure(), using this new
function.
Move the configuration of control queue in the configure callback.
This is needed by next commit, which introduces the reinitialization
of the device in the configure callback to change the feature flags.
Therefore, the control queue will have to be restarted at the same
place.
As virtio_dev_cq_qu
Add the ability to reset the virtio device in the configure callback
if the features flag changed since previous reset. This will be possible
with the introduction of offload support in next commits.

This function can be used to calculate the checksum of data embedded in
mbuf, that can be composed of several segments.
This function will be used by the virtio pmd in next commits to calculate
the checksum in software in case the protocol is not recognized.

Following discussions in [1] and [2], introduce a new bit to
describe the Rx checksum status in mbuf.
Before this patch, only one flag was available:
PKT_RX_L4_CKSUM_BAD: L4 cksum of RX pkt. is not OK.
And same for L3:
PKT_RX_IP_CKSUM_BAD: IP cksum of RX pkt. is not OK.
This had 2 issues:
-
When receiving coalesced packets in virtio, the original size of the
segments is provided. This is a useful information because it allows to
resegment with the same size.
Add a RX new flag in mbuf, that can be set when packets are coalesced by
a hardware or virtual driver when the m->tso_segsz fie
In csumonly engine, display the value of LRO segment if the
LRO flag is set.

Hello DPDK Developers,
Financial Services Industry which is pretty eager for several DPDK
features especially low latency while high throughput. The major issue
so far for increasing DPDK adoption there is requirement for several

The hard requirement of financial services industry is accurate
timestamping aligned with the packet itself. This patch is to satisfy
this requirement:
- include uint64_t timestamp field into rte_mbuf with minimal impact to
throughput/latency. Keep it just simple uint64_t in ns (more than 580
Accurate RX timestaping is minimal requirement for several important

packet capture.
Support of periodic time synchronization with system time and adjusting
clock deviation was also added. We assume the system is synchronized by
Implemented two methods of control
- by --enable-timestamps CL testpmd application we can enable timestamping
for all ports;
- in interactive mode port config timestamps on|off is able to
configure timestamping per specific port.
The control doesn't interact with IEEE1588 PTP implementation

The note i.e. "The dpdk-pdump tool can only be used in
conjunction with a primary process which has the packet
capture framework initialized already" is added to
doc/guides/sample_app_ug/pdump.rst to facilitate
easy understanding on the usage of the tool.
