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.

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.

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).

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

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

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.
Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.
Update documentation for replacing an example referring to
PMD_REGISTER_DRIVER.

As discussed in the past release, driver names are modified
to be more consistent, and the future driver should follow
this new convention.
Driver names consist of:
"driver category"_"driver folder name"_"optional extra name".
For example:
- Crypto null driver -> "crypto_null"
- Network IXGBE VF driver -> "net_ixgbe_vf"

Following discussions on the mailing list [1] and since nobody stood up to
implement the necessary cleanups, here is the ivshmem integration removal.
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.

As no other mempool ABI change is planned in 16.11, it is better

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
...
The output RST table matches the existing table with the column
headers sorted.

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).

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. */

The right name of ethdev should be dpdk_netdev. However:
1/ We are using rte_ prefix in the code and library names.
2/ The API uses rte_ethdev
That's why 16.11 will just have the rte_ prefix prepended to
the library filename as every other libraries.

Driver names for all the supported devices in DPDK do not have
a naming convention. Some are using a prefix, some are not
and some have long names. Driver names are used when creating
virtual devices, so it is useful to have consistency in the names.
