f8244c6399 ethdev: increase port id range
Extend port_id definition from uint8_t to uint16_t in lib and drivers
data structures, specifically rte_eth_dev_data. Modify the APIs,
drivers and app using port_id at the same time.

Fix some checkpatch issues from the original code and remove some
unnecessary cast operations.

release_17_11 and deprecation docs have been updated in this patch.

3cf5eb1546 service: fix and refactor atomic service accesses
This commit fixes an issue in the service runner function,
where the atomic value was not cleared on exiting the service
function. This resulted in future attempts to run the service
to appear like the function was running, however it was in
reality deadlocked.

This commit refactors the atomic handling to be more readable,
by splitting the implementation code into a new static inline
function. The remaining flow control of atomics in the existing
function is refactored for readability.

b17def6c2b doc: announce API change in crypto driver allocation
rte_cryptodev_allocate_driver() function gets one parameter
(rte_driver), as the cryptodev_driver structure is
allocated inside the function with rte_malloc.

This function is called from a constructor function,
when crypto PMDs are registered.
If malloc fails, there is no way to recover from it,
so it is better to allocate this structure
statically, in each PMD.

Therefore, it is required to add an extra parameter in
this function, to also get a pointer to this structure.

caa570db61 doc: announce change to make DPDK IOVA aware
When we run DPDK on guest or VFIO mode on host,
the dpdk library or device will not be directly accessing
the physical address. Instead, the device does go through
an IO address translation memory management unit. On x86,
we call it as IOMMU and on ARM as SMMU.

More details:
http://osidays.com/osidays/wp-content/uploads/2014/12/Final_OSI2014_IOMMU_DetailedView_Sanil_Anurup.pdf

Based on discussion in the following thread
http://dpdk.org/ml/archives/dev/2017-July/070850.html

We would like to change reference to physical address to more
appropriate name as with IOMMU/SMMU with
the device won't be dealing directly with the physical address.

An ABI change is planned for 17.11 to change following
data structure or functions to more appropriate name.
Currently planned to change it iova as instead of phys

Please note: The change will be only for the name and
functional aspects of the API will remain same.

Following functions/data structures name may change.
This list is based on v17.05-rc1. It may change based on v17.11 code base.

0d2cbe59b7 lib/gro: support TCP/IPv4
In this patch, we introduce five APIs to support TCP/IPv4 GRO.
- gro_tcp4_reassemble: reassemble an inputted TCP/IPv4 packet.
- gro_tcp4_tbl_create: create a TCP/IPv4 reassembly table, which is used
    to merge packets.
- gro_tcp4_tbl_destroy: free memory space of a TCP/IPv4 reassembly table.
- gro_tcp4_tbl_pkt_count: return the number of packets in a TCP/IPv4
    reassembly table.
- gro_tcp4_tbl_timeout_flush: flush timeout packets from a TCP/IPv4
    reassembly table.

TCP/IPv4 GRO API assumes all inputted packets are with correct IPv4
and TCP checksums. And TCP/IPv4 GRO API doesn't update IPv4 and TCP
checksums for merged packets. If inputted packets are IP fragmented,
TCP/IPv4 GRO API assumes they are complete packets (i.e. with L4
headers).

In TCP/IPv4 GRO, we use a table structure, called TCP/IPv4 reassembly
table, to reassemble packets. A TCP/IPv4 reassembly table includes a key
array and a item array, where the key array keeps the criteria to merge
packets and the item array keeps packet information.

One key in the key array points to an item group, which consists of
packets which have the same criteria value. If two packets are able to
merge, they must be in the same item group. Each key in the key array
includes two parts:
- criteria: the criteria of merging packets. If two packets can be
    merged, they must have the same criteria value.
- start_index: the index of the first incoming packet of the item group.

Each element in the item array keeps the information of one packet. It
mainly includes three parts:
- firstseg: the address of the first segment of the packet
- lastseg: the address of the last segment of the packet
- next_pkt_index: the index of the next packet in the same item group.
    All packets in the same item group are chained by next_pkt_index.
    With next_pkt_index, we can locate all packets in the same item
    group one by one.

To process an incoming packet needs three steps:
a. check if the packet should be processed. Packets with one of the
    following properties won't be processed:
	- FIN, SYN, RST, URG, PSH, ECE or CWR bit is set;
	- packet payload length is 0.
b. traverse the key array to find a key which has the same criteria
    value with the incoming packet. If find, goto step c. Otherwise,
    insert a new key and insert the packet into the item array.
c. locate the first packet in the item group via the start_index in the
    key. Then traverse all packets in the item group via next_pkt_index.
    If find one packet which can merge with the incoming one, merge them
    together. If can't find, insert the packet into this item group.

e996506a1c lib/gro: add Generic Receive Offload API framework
Generic Receive Offload (GRO) is a widely used SW-based offloading
technique to reduce per-packet processing overhead. It gains
performance by reassembling small packets into large ones. This
patchset is to support GRO in DPDK. To support GRO, this patch
implements a GRO API framework.

To enable more flexibility to applications, DPDK GRO is implemented as
a user library. Applications explicitly use the GRO library to merge
small packets into large ones. DPDK GRO provides two reassembly modes.
One is called lightweight mode, the other is called heavyweight mode.
If applications want to merge packets in a simple way and the number
of packets is relatively small, they can use the lightweight mode.
If applications need more fine-grained controls, they can choose the
heavyweight mode.

rte_gro_reassemble_burst is the main reassembly API which is used in
lightweight mode and processes N packets at a time. For applications,
performing GRO in lightweight mode is simple. They just need to invoke
rte_gro_reassemble_burst. Applications can get GROed packets as soon as
rte_gro_reassemble_burst returns.

rte_gro_reassemble is the main reassembly API which is used in
heavyweight mode and tries to merge N inputted packets with the packets
in GRO reassembly tables. For applications, performing GRO in heavyweight
mode is relatively complicated. Before performing GRO, applications need
to create a GRO context object, which keeps reassembly tables of
desired GRO types, by rte_gro_ctx_create. Then applications can use
rte_gro_reassemble to merge packets. The GROed packets are in the
reassembly tables of the GRO context object. If applications want to get
them, applications need to manually flush them by flush API.

4969f5914c devargs: introduce new parsing helper
Introduce a more versatile helper to parse device strings. This
helper expects a generic rte_devargs structure as storage in order not
to require API changes in the future, should this structure be
updated.

The old equivalent function is thus being deprecated, as its API does
not allow to accompany rte_devargs evolutions.

A deprecation notice is issued.

This new helper will parse bus information as well as device name and
device parameters. It does not allocate an rte_devargs structure and
expects one to be given as input.

6d1729de71 app/testeventdev: introduce dpdk-test-eventdev app
The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK)
application that allows exercising various eventdev use cases. This
application has a generic framework to add new eventdev based test cases
to verify functionality and measure the performance parameters of DPDK
eventdev devices.

This patch adds the skeleton of the dpdk-test-eventdev application.

f7db6f821e cryptodev: add mempool pointer in queue pair setup
The session mempool pointer is needed in each queue pair,
if session-less operations are being handled.
Therefore, the API is changed to accept this parameter,
as the session mempool is created outside the
device configuration function, similar to what ethdev
does with the rx queues.

b3bbd9e5f2 cryptodev: support device independent sessions
Change crypto device's session management to make it
device independent and simplify architecture when session
is intended to be used on more than one device.

Sessions private data is agnostic to underlying device
by adding an indirection in the sessions private data
using the crypto driver identifier.
A single session can contain indirections to multiple device types.

New function rte_cryptodev_sym_session_init has been created,
to initialize the driver private session data per driver to be
used on a same session, and rte_cryptodev_sym_session_clear
to clear this data before calling rte_cryptodev_sym_session_free.
