This is an ABI change notice for DPDK 17.08 in ethdev
about changes in rte_eth_txmode structure.
Currently Tx offloads are enabled by default, and can be disabled
using ETH_TXQ_FLAGS_NO* flags. This behaviour is not consistent with
the Rx side where the Rx offloads are disabled by default and enabled
according to bit field in rte_eth_rxmode structure.
The proposal is to disable the Tx offloads by default, and provide
a way for the application to enable them in rte_eth_txmode structure.
Besides of making the Tx configuration API more consistent for
applications, PMDs will be able to provide a better out of the
box performance.

doc: announce ABI change for device parameters
The PCI and virtual bus are planned to be moved to the generic
drivers/bus directory in v17.08. For this change to be possible, the EAL
must be made completely independent.
The rte_devargs structure currently holds device representation internal
to those two busses. It must be made generic before this work can be
completed.
Instead of using either a driver name for a vdev or a PCI address for a
PCI device, a devargs structure will have to be able to describe any
possible device on all busses, without introducing dependencies on
any bus-specific device representation. This will break the ABI for this
structure.
Additionally, an evolution will occur regarding the device parsing
from the command-line. A user must be able to set which bus will handle
which device, and this setting is integral to the definition of a
device.
The format has not yet been formally defined, but a proposition will
follow soon for a new command line parameter format for all devices.

of levels of warning which are triggered depending on the type of message
used, with level 3 being the default. To accept a wider range of possible

2. GCC also warns about an snprintf where there may be truncation and the
return value is not checked. Given that we often use snprintf in DPDK in

usertools: remove devbind module search corner cases
The existing code used to search for module files via modinfo has
several corner cases which can result in it failing where it should be
successful.
The call to lower() would cause results returned by 'modinfo' to be
forced to lowercase, results which were subsequently passed to
exists() which is case sensitive. This was most likely done to capture
all variants of failure strings modinfo might return
(ie. ERROR/Error/error/...) without thought negative effect to the
later call to exists(). For many this is a nonissue but if the module
path included non-lowercase alpha characters, something which is
easily possible with a non-lowercase kernel-extraversion string, this
would cause an issue.
We could move the call to lower() to the check for "error" but this
still leaves possible corner cases, for modules or module paths with
'error' in them.
Instead we will prevent modinfo's stderr from being used as a "good
value" for path, meaning we either get a valid path from modinfo, or
nothing at all. This removes all corner cases.
Ultimately these preliminary checks are unnecessary as exists() will
only return True if it is passed a valid path, passing it modinfo's
stderr would fail. In keeping with the original code, however, we do
some preliminary checks, but we are now free of corner cases.

ethdev: retrieve xstats by ID
Extended xstats API in ethdev library to allow grouping of stats
logically so they can be retrieved per logical grouping managed
by the application.
Added new functions rte_eth_xstats_get_names_by_id and
rte_eth_xstats_get_by_id using additional arguments (in compare
to rte_eth_xstats_get_names and rte_eth_xstats_get) - array of ids
and array of values.
doc: add description for modified xstats API
Documentation change for new extended statistics API functions.
The old API only allows retrieval of *all* of the NIC statistics
at once. Given this requires a MMIO read PCI transaction per statistic
it is an inefficient way of retrieving just a few key statistics.
Often a monitoring agent only has an interest in a few key statistics,
and the old API forces wasting CPU time and PCIe bandwidth in retrieving
*all* statistics; even those that the application didn't explicitly
show an interest in.
The new, more flexible API allow retrieval of statistics per ID.
If a PMD wishes, it can be implemented to read just the required
NIC registers. As a result, the monitoring application no longer wastes
PCIe bandwidth and CPU time.

doc: revise sample testpmd flow commands
Stop port before enabling QinQ.
Add commands to set inner and outer TPID's and start port.
Remove TPID's from flow validate and and flow create commands.

net/tap: fix support for large Rx queues
Rx queues configured with more than 1023 descriptors cause readv() calls to
fail due to more iovec entries than permitted by the kernel. As a result,
no packets can be received.
Quietly limit internal Rx queue size to the maximum number of iovec entries
to fix this issue.

net/thunderx: fix deadlock in Rx path
RBDR buffers are refilled when SW consumes the buffers from CQ.
This creates deadlock case when CQ buffers exhausted due to lack
of RBDR buffers. Fix is to refill the RBDR when rx_free_thresh
meet, irrespective of the number of CQ buffers consumed.
