82010ef55e app/testpmd: make txonly mode generate multiple flows
Testpmd can generate multiple flows without taking much cost and this
could be a simple traffic generator for developer's quick tests.
If "--txonly-multi-flow" is specified in the command line, IP source
address is varied to generate multiple flows.

ad97ceece1 ethdev: add min/max MTU to device info
This addresses the usability issue raised by OVS at DPDK Userspace
summit. It adds general min/max MTU into device info. For compatibility,
and to save space, it fits in a hole in existing structure.

The initial version sets max MTU to normal Ethernet, it is up to
PMD to set larger value if it supports Jumbo frames.

Also remove the deprecation notice introduced in 18.11 regarding this
change and bump ethdev ABI version.

c33a675b62 bus: introduce device level DMA memory mapping
The DPDK APIs expose 3 different modes to work with memory used for DMA:

1. Use the DPDK owned memory (backed by the DPDK provided hugepages).
This memory is allocated by the DPDK libraries, included in the DPDK
memory system (memseg lists) and automatically DMA mapped by the DPDK
layers.

2. Use memory allocated by the user and register to the DPDK memory
systems. Upon registration of memory, the DPDK layers will DMA map it
to all needed devices. After registration, allocation of this memory
will be done with rte_*malloc APIs.

3. Use memory allocated by the user and not registered to the DPDK memory
system. This is for users who wants to have tight control on this
memory (e.g. avoid the rte_malloc header).
The user should create a memory, register it through rte_extmem_register
API, and call DMA map function in order to register such memory to
the different devices.

The scope of the patch focus on #3 above.

Currently the only way to map external memory is through VFIO
(rte_vfio_dma_map). While VFIO is common, there are other vendors
which use different ways to map memory (e.g. Mellanox and NXP).

The work in this patch moves the DMA mapping to vendor agnostic APIs.
Device level DMA map and unmap APIs were added. Implementation of those
APIs was done currently only for PCI devices.

For PCI bus devices, the pci driver can expose its own map and unmap
functions to be used for the mapping. In case the driver doesn't provide
any, the memory will be mapped, if possible, to IOMMU through VFIO APIs.

Application usage with those APIs is quite simple:
* allocate memory
* call rte_extmem_register on the memory chunk.
* take a device, and query its rte_device.
* call the device specific mapping function for this device.

Future work will deprecate the rte_vfio_dma_map and rte_vfio_dma_unmap
APIs, leaving the rte device APIs as the preferred option for the user.

e17e6d31ca doc: make RTE_NEXT_ABI optional in guidelines
Initial process requires oncoming changes described in deprecation
notice should be implemented in a RTE_NEXT_ABI gated way.

This has been discussed in technical board, and since this can cause a
multiple #ifdef blocks in multiple locations of the code, can be
confusing specially for the modifications that requires data structure
changes. Anyway this was not happening in practice.

Making RTE_NEXT_ABI usage more optional based on techboard decision:
http://mails.dpdk.org/archives/dev/2019-January/123519.html

The intention with using RTE_NEXT_ABI was to provide more information
to the user about planned changes, and force developer to think more in
coding level. Since RTE_NEXT_ABI become optional, now the preferred way
to do this is, if possible, sending changes, described in deprecation
notice, as a separate patch and reference it in deprecation notice.

99889bd852 ci: introduce Travis builds for GitHub repositories
GitHub is a service used by developers to store repositories.  GitHub
provides service integrations that allow 3rd party services to access
developer repositories and perform actions.  One of these services is
Travis-CI, a simple continuous integration platform.

This series introduces the ability for any github mirrors of the DPDK
project, including developer mirrors, to kick off builds under the
travis CI infrastructure.  For now, this just means compilation - no
other kinds of automated run exists yet.  In the future, this can be
expanded to execute and report results for any test-suites that might
exist.

This is a simple initial implementation of a travis build for the DPDK
project.  It doesn't require any changes from individual developers to
enable, but will allow those developers who opt-in to GitHub and the
travis service to get automatic builds for every push they make.

The files added under .ci/ exist so that in the future, other CI
support platforms (such as cirrus, appveyor, etc.) could have a common
place to put their requisite scripts without polluting the main tree.

27e71c7fdc cryptodev: restore crypto op alignment and layout
in 18.08 new cache-aligned structure rte_crypto_asym_op was introduced.
As it also was included into rte_crypto_op, it caused implicit change
in rte_crypto_op layout and alignment: now rte_crypto_op is cache-line
aligned has a hole of 40/104 bytes between phys_addr and sym/asym op.
It looks like unintended ABI breakage, plus such change can cause
negative performance effects:
- now status and sym[0].m_src lies on different cache-lines, so
  post-process code would need extra cache-line read.
- new alignment causes grow of the space requirements and cache-line
  reads/updates for structures that contain rte_crypto_op inside.
As there seems no actual need to have rte_crypto_asym_op cache-line
aligned, and rte_crypto_asym_op is not intended to be used on it's own -
the simplest fix is just to remove cache-line alignment for it.
As the immediate positive effect: on IA ipsec-secgw performance increased
by 5-10% (depending on the crypto-dev and algo used).
My guess that on machines with 128B cache-line and lookaside-protocol
capable crypto devices the impact will be even more noticeable.

Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both

4445a0f4c7 net/enic: fix inner packet matching
Inner packet matching is currently buggy in many cases.

1. Mishandling null spec ("match any").
The copy_item functions do nothing if spec is null. This is incorrect,
as all patterns should be appended to the L5 pattern buffer even for
null spec (treated as all zeros).

2. Accessing null spec causing segfault.

3. Not setting protocol fields.
The NIC filter API currently has no flags for "match inner IPv4, IPv6,
UDP, TCP, and so on". So, the driver needs to explicitly set EtherType
and IP protocol fields in the L5 pattern buffer to avoid false
positives (e.g. reporting IPv6 as IPv4).

Instead of keep adding "if inner, do something differently" cases to
the existing copy_item functions, introduce separate functions for
inner packet patterns and address the above issues in those
functions. The changes to the previous outer-packet copy_item
functions are mechanical, due to reduced indentation.

which does pattern match on packet data immediately following the
outer L4 header. Accept raw items for these limited use cases.

5af7af4d6b net/enic: enable limited passthru flow action
Some apps like VPP use PASSTHRU+MARK flow rules to offload packet
matching to the NIC. Just like MARK+RSS used by OVS-DPDK and others,
PASSTHRU+MARK is used to "mark and then receive normally". Recent VIC
adapters support such flow rules, so enable PASSTHRU for this limited
use case.

e9434f6f60 net/enic: enable limited RSS flow action
Some apps like OVS-DPDK use MARK+RSS flow rules in order to offload
packet matching to the NIC. The RSS action in such flow rules simply
indicates "receive packet normally", not trying to override the port
wide RSS. The action is included in the flow rules simply to terminate
them, as MARK is not a fate-deciding action. And, the RSS action has a
most basic config: default hash, level, types, null key, and identity
queue mapping.

Recent VIC adapters can support these "mark and receive" flow
rules. So, enable support for RSS action for this limited use case.

e7347a8aff net/enic: allow flow mark ID 0
The driver currently accepts mark ID 0 but does not report it in
matching packet's mbuf. For example, the following testpmd command
succeeds. But, the mbuf of a matching IPv4 UDP packet does not have
PKT_RX_FDIR_ID set.

flow create 0 ingress pattern ... actions mark id 0 / queue index 0 / end

The problem has to do with mapping mark IDs (32-bit) to NIC filter
IDs. Filter ID is currently 16-bit, so values greater than 0xffff are
rejected. The firmware reserves filter ID 0 for filters that do not
mark (e.g. steer w/o mark). And, the driver reserves 0xffff for the
flag action. This leaves 1...0xfffe for app use.

It is possible to simply reject mark ID 0 as unsupported. But, 0 is
commonly used (e.g. OVS-DPDK and VPP). So, when adding a filter, set
filter ID = mark ID + 1 to support mark ID 0. The receive handler
subtracts 1 from filter ID to get back the original mark ID.

c3568ea376 eal: restrict control threads to startup CPU affinity
Spawning the ctrl threads on anything that is not part of the eal
coremask is not that polite to the rest of the system, especially
when you took good care to pin your processes on cpu resources with
tools like taskset (linux) / cpuset (freebsd).

Rather than introduce yet another eal options to control on which cpu
those ctrl threads are created, let's take the startup cpu affinity
as a reference and remove the eal coremask from it.
If no cpu is left, then we default to the master core.

The cpuset is computed once at init before the original cpu affinity
is lost.

Introduced a RTE_CPU_AND macro to abstract the differences between linux
and freebsd respective macros.

Examples in a 4 cores FreeBSD vm:
