90f12e7a4d net/i40evf: fix return value if admin queue command fails
Previously, if an adminq message is sent successfully, but no response is
received, function "i40evf_execute_vf_cmd" will return without error.
The root cause is value "err" is overwritten. This patch fixes this by
ensuring the value of err is set appropriately for each cmd.

4f213197ef mk: fix external dependencies of crypto drivers
When linking drivers as shared libraries, the dependencies need
to be marked as DT_NEEDED entries.

The crypto dependencies (libsso and libIPSec) are static libraries.
To make them linked in the shared PMDs, the code must relocatable:
    - libIPSec_MB.a must be built with -fPIC
    - libsso_kasumi.a must be built with KASUMI_CFLAGS=-DKASUMI_C

b81026f1e7 net/virtio: fix used index retrieved only once
In the following loop:
    while (vq->vq_used_cons_idx != vq->vq_ring.used->idx) {
            ...
    }
There is no external function call or any explict memory barrier
in the loop, the re-read of used->idx might be optimized and only
be retrieved once.

Use of voaltile normally should be prohibited, and access_once
is Linux kernel's style to handle this issue; Once we have that
macro in DPDK, we could change to that style.

virtio_recv_mergable_pkts might also have the same issue, so fix

f9b9d1a557 net/virtio-user: add multiple queues in device emulation
The main purpose of this patch is to enable multi-queue. But
multi-queue requires ctrl-queue so that driver can send how many
queues will be enabled through ctrl-queue messages.

So we partially implement ctrl-queue to handle control command
with class of VIRTIO_NET_CTRL_MQ and with cmd of
VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET to handle mq support. This patch
provides a function, virtio_user_handle_cq(), for driver to handle
ctrl-queue messages.

Besides, multi-queue requires VIRTIO_NET_F_MQ and VIRTIO_NET_F_CTRL_VQ
are enabled when we do feature negotiation.

ce2eabdd43 net/virtio-user: add virtual device
Add a new virtual device named virtio-user, which can be used just like
eth_ring, eth_null, etc. To reuse the code of original virtio, we do
some adjustment in virtio_ethdev.c, such as remove key _static_ of
eth_virtio_dev_init() so that it can be reused in virtual device; and
we add some check to make sure it will not crash.

Configured parameters include:
  - queues (optional, 1 by default), number of queue pairs, multi-queue
    not supported for now.
  - cq (optional, 0 by default), not supported for now.
  - mac (optional), random value will be given if not specified.
  - queue_size (optional, 256 by default), size of virtqueues.
  - path (madatory), path of vhost user.

When enable CONFIG_RTE_VIRTIO_USER (enabled by default), the compiled
library can be used in both VM and container environment.

Examples:
path_vhost=<path_to_vhost_user> # use vhost-user as a backend

sudo ./examples/l2fwd/build/l2fwd -c 0x100000 -n 4 \
    --socket-mem 0,1024 --no-pci --file-prefix=l2fwd \
    --vdev=virtio-user0,mac=00:01:02:03:04:05,path=$path_vhost -- -p 0x1

Known issues:
 - Control queue and multi-queue are not supported yet.
 - Cannot work with --huge-unlink.
 - Cannot work with no-huge.
 - Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8)
   hugepages.
 - Root privilege is a must (mainly becase of sorting hugepages according
   to physical address).
 - Applications should not use file name like HUGEFILE_FMT ("%smap_%d").
 - Cannot work with vhost-net backend.

configuration space, this virtual pci driver will rd/wr the virtual
device struct virtio_user_hw, and when necessary, invokes APIs provided
by device emulation later to start/stop the device.

f24f8f9fee net/virtio: allow virtual address to fill vring descriptors
This patch is related to how to calculate relative address for vhost
backend.

The principle is that: based on one or multiple shared memory regions,
vhost maintains a reference system with the frontend start address,
backend start address, and length for each segment, so that each
frontend address (GPA, Guest Physical Address) can be translated into
vhost-recognizable backend address. To make the address translation
efficient, we need to maintain as few regions as possible. In the case
of VM, GPA is always locally continuous. But for some other case, like
virtio-user, GPA continuous is not guaranteed, therefore, we use virtual
address here.

It basically means:
  a. when set_base_addr, VA address is used;
  b. when preparing RX's descriptors, VA address is used;
  c. when transmitting packets, VA is filled in TX's descriptors;
  d. in TX and CQ's header, VA is used.

31dc62ef39 net/i40e: fetch extended statistics with integer ids
The current extended ethernet statistics fetching involve doing several
string operations, which causes performance issues if there are lots of
statistics and/or network interfaces. This patch changes the i40e driver
to use the new API that seperates name string and value queries.

281ccccb1a virtio: fix PCI accesses for ppc64 in legacy mode
Although ppc supports both endianesses, qemu supposes that the cpu is
big endian and enforces this for the virtio-net stuff.

Fix PCI accesses in legacy mode. Only ppc64le is supported at the moment.

b37b528d95 mbuf: add new Rx flags for stripped VLAN
The behavior of PKT_RX_VLAN_PKT was not very well defined, resulting in
PMDs not advertising the same flags in similar conditions.

Following discussion in [1], introduce 2 new flags PKT_RX_VLAN_STRIPPED
and PKT_RX_QINQ_STRIPPED that are better defined:

  PKT_RX_VLAN_STRIPPED: a vlan has been stripped by the hardware and its
  tci is saved in mbuf->vlan_tci. This can only happen if vlan stripping
  is enabled in the RX configuration of the PMD.

For now, the old flag PKT_RX_VLAN_PKT is kept but marked as deprecated.
It should be removed from applications and PMDs in a future revision.

This patch also updates the drivers. For PKT_RX_VLAN_PKT:

- e1000, enic, i40e, mlx5, nfp, vmxnet3: done, PKT_RX_VLAN_PKT already
  had the same meaning than PKT_RX_VLAN_STRIPPED, minor update is
  required.
- fm10k: done, PKT_RX_VLAN_PKT already had the same meaning than
  PKT_RX_VLAN_STRIPPED, and vlan stripping is always enabled on fm10k.
- ixgbe: modification done (vector and normal), the old flag was set
  when a vlan was recognized, even if vlan stripping was disabled.
- the other drivers do not support vlan stripping.

For PKT_RX_QINQ_PKT, it was only supported on i40e, and the behavior was
already correct, so we can reuse the same bit value for
PKT_RX_QINQ_STRIPPED.

53c3c30c11 pci: allow to override sysfs path
The SYSFS_PCI_DEVICES is a constant that makes the PCI testing
difficult as it points to an absolute path. We remove using this
constant and introducing a function pci_get_sysfs_path that gives
the same value. However, the user can pass a SYSFS_PCI_DEVICES env
variable to override the path. It is now possible to create a fake
sysfs hierarchy for testing.

bf5a46fa59 mk: generate internal library dependencies
Up to now dependencies between DPDK internal libraries have been
untracked at shared library level, requiring applications to know
about library internal dependencies and often consequently overlinking.

Since the dependencies are already recorded for build ordering in the
makefiles with DEPDIRS-y we can use that information to generate LDLIBS
entries for internal libraries automatically.

Also revert commit 8180554d82 ("vhost: fix linkage of driver with
library") which is made redundant by this change.
