faf08c8b0f examples/performance-thread: add packet type parsing
Last changes in Niantic and Fortville NIC drivers causes that
vector Rx path is chosen by default in l3fwd-thread application.
This path doesn't support propagation of hw packet type recognition
to the packet_type field in mbuf, and packets cannot be classified
properly.

The approach to solve this problem is similar to the commit:
71a7e2424e ("examples/l3fwd: fix using packet type blindly").

To use sw packet analyzer, new command line option "--parse-ptype" is
introduced.

e0ef2aecde doc: simplify l3fwd example guide
L3 Forwarding sample app user guides have some inconsistencies
between the example command line and the configuration table.
Also, they were showing too complicated configuration, using two
different NUMA nodes for two ports, which will probably lead
to performance drop due to use cross-socket channel.

This patch simplifies the configuration of these examples,
by using a single NUMA node and a single queue per port.

26b683b4f7 net/virtio: setup Rx queue interrupts
This patch mainly allocates structure to store queue/irq mapping,
and configure queue/irq mapping down through PCI ops. It also creates
eventfds for each Rx queue and tell the kernel about the eventfd/intr
binding.

Note: So far, we hard-code 1:1 queue/irq mapping (each rx queue has
one exclusive interrupt), like this:
  vec 0 -> config irq
  vec 1 -> rxq0
  vec 2 -> rxq1
  ...

which means, the "vectors" option of QEMU should be configured with
a value >= N+1 (N is the number of the queue pairs).

6d890f8ab5 net/virtio: fix multiple process support
The introduce of virtio 1.0 support brings yet another set of ops, badly,
it's not handled correctly, that it breaks the multiple process support.

The issue is the data/function pointer may vary from different processes,
and the old used to do one time set (for primary process only). That
said, the function pointer the secondary process saw is actually from the
primary process space. Accessing it could likely result to a crash.

Kudos to the last patches, we now be able to maintain those info that may
vary among different process locally, meaning every process could have its
own copy for each of them, with the correct value set. And this is what
this patch does:

- remap the PCI (IO port for legacy device and memory map for modern
  device)

- set vtpci_ops correctly

After that, multiple process would work like a charm. (At least, it
passed my fuzzy test)

Fixes: b8f04520ad ("virtio: use PCI ioport API")
Fixes: d5bbeefca8 ("virtio: introduce PCI implementation structure")
Fixes: 6ba1f63b5a ("virtio: support specification 1.0")

PMDs to process and validate flow rules.

Benefits:

- A unified API is easier to program for, applications do not have to be
  written for a specific filter type which may or may not be supported by
  the underlying device.

- The behavior of a flow rule is the same regardless of the underlying
  device, applications do not need to be aware of hardware quirks.

- Extensible by design, API/ABI breakage should rarely occur if at all.

- Documentation is self-standing, no need to look up elsewhere.

Existing filter types will be deprecated and removed in the near future.

5d8f0baf69 log: do not drop debug logs at compile time
Today, all logs whose level is lower than INFO are dropped at
compile-time. This prevents from enabling debug logs at runtime using
--log-level=8.

The rationale was to remove debug logs from the data path at
compile-time, avoiding a test at run-time.

This patch changes the behavior of RTE_LOG() to avoid the compile-time
optimization, and introduces the RTE_LOG_DP() macro that has the same
behavior than the previous RTE_LOG(), for the rare cases where debug
logs are in the data path.

So it is now possible to enable debug logs at run-time by just
specifying --log-level=8. Some drivers still have special compile-time
options to enable more debug log. Maintainers may consider to
remove/reduce them.

3bac1dbc1e doc: announce iomem and ioport removal from igb_uio
In igb_uio, iomem is mapped, and both ioport and io mem are recorded
into uio framework (then into sysfs files), which is duplicated with
what Linux has already provided for user space, and makes the code
too complex.

For iomem, DPDK user space code never opens or reads files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/maps/. Instead,
/sys/pci/bus/devices/xxxx:xx:xx.x/resourceY are used to map device
memory.

For ioport, non-x86 platforms cannot read from files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/portio/ directly, because
non-x86 platforms need to map port region for access in user space,
see non-x86 version pci_uio_ioport_map(). x86 platforms can use the
the same way as uio_pci_generic.

This will remove iomem and ioport mapping in igb_uio kernel module,
and adjusts the iomem implementation in both igb_uio and
uio_pci_generic:
  - for x86 platform, get ports info from /proc/ioports;
  - for non-x86 platform, map and get ports info by pci_uio_ioport_map().

Note: this will affect those applications who are using files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/maps/ and
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/portio/.

aaffc740ec net/ixgbe: fix VF VLAN insert API
The final parameter to rte_pmd_ixgbe_set_vf_vlan_insert is uint8_t
and treated as a binary flag when it needs to be a uint16_t
and treated as a VLAN id.  The data sheet (sect 8.2.3.27.13) describes
the right most 16 bits as the VLAN id that is to be inserted; the
16.11  code is accepting only a 1 or 0 thus effectively only
allowing the VLAN id 1 to be inserted (0 disables the insertion
setting).

This patch changes the final parm name to represent the data that
is being accepted (vlan_id), changes the type to permit all valid
VLAN ids, and validates the parameter based on the range of 0 to
4095. Corresponding changes to prototype and documentation in the
.h file.

dfbd6a9cb5 net/enic: extend flow director support for 1300 series
1300 series Cisco adapter firmware version 2.0(13) for UCS
C-series servers and 3.1(2) for blade servers supports more
filtering capabilities. The feature can be enabled via Cisco
CIMC or USCM with the 'advanced filters' radio button. When
enabled, the these additional flow director modes are available:
	RTE_ETH_FLOW_NONFRAG_IPV4_OTHER
	RTE_ETH_FLOW_NONFRAG_IPV4_SCTP
	RTE_ETH_FLOW_NONFRAG_IPV6_UDP
	RTE_ETH_FLOW_NONFRAG_IPV6_TCP
	RTE_ETH_FLOW_NONFRAG_IPV6_SCTP
	RTE_ETH_FLOW_NONFRAG_IPV6_OTHER

Changes:
- Detect and set an 'advanced filters' flag dependent on the adapter
  capability.
- Implement RTE_ETH_FILTER_INFO filter op to return the flow types
  available dependent on whether advanced filters are enabled.
- Use a function pointer to select how filters are added to the adapter:
  copy_fltr_v1() for older firmware/adapters or copy_fltr_v2() for
  adapters which support advanced filters.
- Apply fdir global masks to filters when in advanced filter mode.
- Update documentation.

5842289a54 mbuf: add new Rx checksum flags
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:
- it was not possible to differentiate "checksum good" from
  "checksum unknown".
- it was not possible for a virtual driver to say "the checksum
  in packet may be wrong, but data integrity is valid".

This patch tries to solve this issue by having 4 states (2 bits)
for the IP and L4 Rx checksums. New values are:

 - PKT_RX_L4_CKSUM_UNKNOWN: no information about the RX L4 checksum
   -> the application should verify the checksum by sw
 - PKT_RX_L4_CKSUM_BAD: the L4 checksum in the packet is wrong
   -> the application can drop the packet without additional check
 - PKT_RX_L4_CKSUM_GOOD: the L4 checksum in the packet is valid
   -> the application can accept the packet without verifying the
      checksum by sw
 - PKT_RX_L4_CKSUM_NONE: the L4 checksum is not correct in the packet
   data, but the integrity of the L4 data is verified.
   -> the application can process the packet but must not verify the
      checksum by sw. It has to take care to recalculate the cksum
      if the packet is transmitted (either by sw or using tx offload)

  And same for L3 (replace L4 by IP in description above).

This commit tries to be compatible with existing applications that
only check the existing flag (CKSUM_BAD).

ab09e04d2c net: add function to get packet type from data
Introduce the function rte_net_get_ptype() that parses a mbuf and
returns its packet type. For now, the following packet types are parsed:
   L2: Ether
   L3: IPv4, IPv6
   L4: TCP, UDP, SCTP

The goal here is to provide a reference implementation for packet type
parsing. This function will be used by testpmd in next commits, allowing
to compare its result with the value given by the hardware.

This function will also be useful when implementing Rx offload support
in virtio pmd. Indeed, the virtio protocol gives the csum start and
offset, but it does not give the L4 protocol nor it tells if the
checksum is relevant for inner or outer. This information has to be
known to properly set the ol_flags in mbuf.

4d6cf2ac93 net/vhost: add extended statistics
This feature adds vhost pmd extended statistics from per port perspective
in order to meet the requirements of the applications such as OVS etc.
RX/TX xstats count the bytes without CRC. This is different from physical
NIC stats with CRC.

The statistics counters are based on RFC 2819 and RFC 2863 as follows:

rx/tx_good_packets
rx/tx_total_bytes
rx/tx_missed_pkts
rx/tx_broadcast_packets
rx/tx_multicast_packets
rx/tx_unicast_packets
rx/tx_undersize_errors
rx/tx_size_64_packets
rx/tx_size_65_to_127_packets;
rx/tx_size_128_to_255_packets;
rx/tx_size_256_to_511_packets;
rx/tx_size_512_to_1023_packets;
rx/tx_size_1024_to_1522_packets;
rx/tx_1523_to_max_packets;
rx/tx_errors
rx_fragmented_errors
rx_jabber_errors
rx_unknown_protos_packets;

No API is changed or added.
rte_eth_xstats_get_names() to retrieve what kinds of vhost xstats are
supported,
rte_eth_xstats_get() to retrieve vhost extended statistics,
rte_eth_xstats_reset() to reset vhost extended statistics.

The usage of vhost pmd xstats is the same as virtio pmd xstats.
for example, when test-pmd application is running in interactive mode
vhost pmd xstats will support the two following commands:

show port xstats all | port_id will show vhost xstats
clear port xstats all | port_id will reset vhost xstats

net/virtio pmd xstats(the function virtio_update_packet_stats) is used
as reference when implementing the feature.

2304dd73d2 vhost: support indirect Tx descriptors
Indirect descriptors are usually supported by virtio-net devices,
allowing to dispatch a larger number of requests.

When the virtio device sends a packet using indirect descriptors,
only one slot is used in the ring, even for large packets.

The main effect is to improve the 0% packet loss benchmark.
A PVP benchmark using Moongen (64 bytes) on the TE, and testpmd
(fwd io for host, macswap for VM) on DUT shows a +50% gain for
zero loss.

On the downside, micro-benchmark using testpmd txonly in VM and
rxonly on host shows a loss between 1 and 4%. But depending on
the needs, feature can be disabled at VM boot time by passing
indirect_desc=off argument to vhost-user device in Qemu.

Following discussions on the mailing list [1] and since nobody stood up to

There is not much to say about this patch, a lot of code is being removed.
The default configuration file for packet_ordering example is replaced with
the "native" x86 file.
The only tricky part is in eal_memory with the memseg index stuff.

More cleanups can be done after this but will come in subsequent patchsets.

9db3f52126 doc: generate NIC overview table from ini files
Convert the NIC feature table in the overview doc into a set of ini
files and add functions into the Sphinx conf.py file to auto-generate
them back into an RST table.

The reason for doing this is to make it easier for PMD maintainers to
update the feature matrix that makes up the table and to avoid
frequent and hard to resolve conflicts in doc/guides/nics/overview.rst.

A NIC/PMD feature matrix is now an ini file like the following:

    $ head doc/guides/nics/nic_features/i40e.ini
    ;
    ; Features of the i40e network driver.
    ;
    [Features]
    Link status          = Y
    Link status event    = Y
    Rx interrupt         = Y
    Queue start/stop     = Y
    ...

8a3433af84 doc: announce vhost-cuse removal
Vhost-cuse was invented before vhost-user exist. The both are actually
doing the same thing: a vhost-net implementation in user space. But they
are not exactly the same thing.

Firstly, vhost-cuse is harder for use; no one seems to care it, either.
Furthermore, since v2.1, a large majority of development effort has gone
to vhost-user. For example, we extended the vhost-user spec to add the
multiple queue support. We also added the vhost-user live migration at
v16.04 and the latest one, vhost-user reconnect that allows vhost app
restart without restarting the guest. Both of them are very important
features for product usage and none of them works for vhost-cuse.

You now see that the difference between vhost-user and vhost-cuse is
big (and will be bigger and bigger as time moves forward), that you
should never use vhost-cuse, that we should drop it completely.

The remove would also result to a much cleaner code base, allowing us
to do all kinds of extending easier.

So here to mark vhost-cuse as deprecated in this release and will be
removed in the next release (v16.11).

ad5fd43ba1 doc: announce ABI change for Tx preparation
This is an ABI deprecation notice for DPDK 16.11 in librte_ether about
changes in rte_eth_dev and rte_eth_desc_lim structures.

As discussed in that thread:

http://dpdk.org/ml/archives/dev/2015-September/023603.html

Different NIC models depending on HW offload requested might impose
different requirements on packets to be TX-ed in terms of:

 - Max number of fragments per packet allowed
 - Max number of fragments per TSO segments
 - The way pseudo-header checksum should be pre-calculated
 - L3/L4 header fields filling
 - etc.

MOTIVATION:
-----------

1) Some work cannot (and didn't should) be done in rte_eth_tx_burst.
   However, this work is sometimes required, and now, it's an
   application issue.

2) Different hardware may have different requirements for TX offloads,
   other subset can be supported and so on.

3) Some parameters (eg. number of segments in ixgbe driver) may hung
   device. These parameters may be vary for different devices.

   For example i40e HW allows 8 fragments per packet, but that is after
   TSO segmentation. While ixgbe has a 38-fragment pre-TSO limit.

4) Fields in packet may require different initialization (like eg. will
   require pseudo-header checksum precalculation, sometimes in a
   different way depending on packet type, and so on). Now application
   needs to care about it.

5) Using additional API (rte_eth_tx_prep) before rte_eth_tx_burst let to
   prepare packet burst in acceptable form for specific device.

6) Some additional checks may be done in debug mode keeping tx_burst
   implementation clean.

PROPOSAL:
---------

To help user to deal with all these varieties we propose to:

1. Introduce rte_eth_tx_prep() function to do necessary preparations of
   packet burst to be safely transmitted on device for desired HW
   offloads (set/reset checksum field according to the hardware
   requirements) and check HW constraints (number of segments per
   packet, etc).

   While the limitations and requirements may differ for devices, it
   requires to extend rte_eth_dev structure with new function pointer
   "tx_pkt_prep" which can be implemented in the driver to prepare and
   verify packets, in devices specific way, before burst, what should to
   prevent application to send malformed packets.

2. Also new fields will be introduced in rte_eth_desc_lim:
   nb_seg_max and nb_mtu_seg_max, providing an information about max
   segments in TSO and non-TSO packets acceptable by device.

   This information is useful for application to not create/limit
   malicious packet.

APPLICATION (CASE OF USE):
--------------------------

1) Application should to initialize burst of packets to send, set
   required tx offload flags and required fields, like l2_len, l3_len,
   l4_len, and tso_segsz

2) Application passes burst to the rte_eth_tx_prep to check conditions
   required to send packets through the NIC.

3) The result of rte_eth_tx_prep can be used to send valid packets
   and/or restore invalid if function fails.

eg.

	for (i = 0; i < nb_pkts; i++) {

		/* initialize or process packet */

		bufs[i]->tso_segsz = 800;
		bufs[i]->ol_flags = PKT_TX_TCP_SEG | PKT_TX_IPV4
				| PKT_TX_IP_CKSUM;
		bufs[i]->l2_len = sizeof(struct ether_hdr);
		bufs[i]->l3_len = sizeof(struct ipv4_hdr);
		bufs[i]->l4_len = sizeof(struct tcp_hdr);
	}

	/* Prepare burst of TX packets */
	nb_prep = rte_eth_tx_prep(port, 0, bufs, nb_pkts);

	if (nb_prep < nb_pkts) {
		printf("tx_prep failed\n");

		/* drop or restore invalid packets */

	}

	/* Send burst of TX packets */
	nb_tx = rte_eth_tx_burst(port, 0, bufs, nb_prep);

	/* Free any unsent packets. */

a5d7a3f77d unify tools naming
The following tools may be installed system-wide.
It may be cleaner and more convenient to find them with the same
dpdk- prefix (especially for autocompletion).
Moreover, the script dpdk_nic_bind.py deserves a new name because it is
not restricted to NICs and can be used for e.g. crypto.

These files are renamed:
pmdinfogen       -> dpdk-pmdinfogen
pmdinfo.py       -> dpdk-pmdinfo.py
dpdk_pdump       -> dpdk-pdump
dpdk_proc_info   -> dpdk-procinfo
dpdk_nic_bind.py -> dpdk-devbind.py
setup.sh         -> dpdk-setup.sh

The tools pmdinfogen, pmdinfo.py and dpdk_pdump are new in 16.07.

The scripts dpdk_nic_bind.py and setup.sh may have been used with
previous releases by end users. That's why a symbolic link still
provide the old name in the installed tools directory.

f6ee75b542 doc: note a pitfall on vhost reconnect feature
The vhost feature negotiation only happens at virtio reset stage, say
when a virtio-net device is firstly initiated, or when DPDK virtio PMD
initiates. That means, if vhost APP restarts after the negotiation and
reconnects, the feature negotiation process will not be triggered again,
meaning the info is lost. To make reconnect work, QEMU simply saves
the negotiated features before the restart and restores it afterwards.

Therefore, the vhost supported features must be exactly the same before
and after the restart. For example, if TSO is disabled and then enabled,
nothing will work and undefined issues might happen.

enabled CONFIG_IO_STRICT_DEVMEM option:

EAL: pci_map_resource():
         cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0):
         Invalid argument (0xffffffffffffffff)

CONFIG_IO_STRICT_DEVMEM is introduced in Linux v4.5 and not enabled
by default:
Linux commit: 90a545e restrict /dev/mem to idle io memory ranges

As a workaround igb_uio can stop reserving PCI memory resources, from
kernel point of view iomem region looks like idle and mmap works
again. This matches uio_pci_generic usage.

With this update device iomem range is not protected against any
other kernel drivers or userspace access. But this  shouldn't
be a problem for dpdk usage module since purpose of the igb_uio
module is to provide userspace access.

ebee5594a3 crypto/kasumi: restrict cipher bit-level operations
KASUMI PMD only supports bit-level cipher operations
when destination buffer is different from the source
(out of place operations). This commit adds a check
in the code to prevent the user from trying to perform
in-place bit-level ciphering.

2bfaec9072 doc: update vhost guide
Mainly on updating vhost-user part: we now support client mode.
Also refine some words, and add a bit more explanation.

And made an emphatic statement that you are suggested to use vhost-user
instead of vhost-cuse, because we have enhanced vhost-user a lot since
v2.2 (Actually, I doubt there are any people still using vhost-cuse)
