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.

On Linux, all huge pages are zeroed by the kernel before
first access by the DPDK application. But on FreeBSD,
the contigmem driver would only zero the contiguous
memory regions during initial driver load.
DPDK commit b78c91751 eliminated the explicit memset()
operation for rte_zmalloc(), which was OK on Linux
because the kernel zeroes the pages during app start,
but this broke FreeBSD when restarting app.
So this patch explicitly zeroes the pages before they are mmap'd,
to ensure equivalent behavior to Linux.

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

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:

2/ The API uses rte_ethdev

the library filename as every other libraries.
