net/nfp: fix mbufs releasing when stop or close
PMDs have the responsibility of releasing mbufs sent through xmit burst
function. NFP PMD attaches those sent mbufs to the TX ring structure,
and it is at the next time a specific ring descriptor is going to be
used when the previous linked mbuf, already transmitted at that point,
is released. Those mbufs belonging to a chained mbuf got its own link
to a ring descriptor, and they are released independently of the mbuf
head of that chain.
The problem is how those mbufs are released when the PMD is stopped or
closed. Instead of releasing those mbufs as the xmit functions does,
this is independently of being in a mbuf chain, the code calls
rte_pktmbuf_free which will release not just the mbuf head in that
chain but all the chained mbufs. The loop will try to release those
mbufs which have already been released again when chained mbufs exist.
This patch fixes the problem using rte_pktmbuf_free_seg instead.

net/vmxnet3: increase Rx data ring descriptor size
Vmxnet3 driver supports receive data ring viz. a set of small sized
buffers that are always mapped by the emulation. If a packet fits into
the receive data ring buffer, the emulation delivers the packet via the
receive data ring.
Increasing the receive data ring descriptor size from 128 to 256
showed performance gains as high as 5% for packets smaller than 256.

- Rx/Tx checksum offloads for both inner and outer packets.
- Rx inner packet type classification.
- TSO.
- Inner RSS.
TX descriptors do not require any changes, except the header length
for TSO. The NIC parses outer/inner packets and performs offloads on
them as necessary. The header length for tunneled TSO includes both
inner and outer headers.
The NIC actually parses and performs the above for NVGRE as well. DPDK
currently has no offload flags for NVGRE, and the hardware has no

net/ifcvf: add ifcvf vDPA driver
The IFCVF vDPA (vhost data path acceleration) driver provides support for
the Intel FPGA 100G VF (IFCVF). IFCVF's datapath is virtio ring compatible,
it works as a HW vhost backend which can send/receive packets to/from
virtio directly by DMA.
Different VF devices serve different virtio frontends which are in
different VMs, so each VF needs to have its own DMA address translation
service. During the driver probe a new container is created, with this
container vDPA driver can program DMA remapping table with the VM's memory
region information.
Key vDPA driver ops implemented:
- ifcvf_dev_config:
Enable VF data path with virtio information provided by vhost lib,
including IOMMU programming to enable VF DMA to VM's memory, VFIO
interrupt setup to route HW interrupt to virtio driver, create notify
relay thread to translate virtio driver's kick to a MMIO write onto HW,
HW queues configuration.
- ifcvf_dev_close:
Revoke all the setup in ifcvf_dev_config.
Live migration feature is supported by IFCVF and this driver enables
it. For the dirty page logging, VF helps to log for packet buffer write,
driver helps to make the used ring as dirty when device stops.
Because vDPA driver needs to set up MSI-X vector to interrupt the
guest, only vfio-pci is supported currently.

net/virtio: skip device probe in vDPA mode
If we want a virtio device to work in vDPA (vhost data path acceleration)
mode, we could add a "vdpa=1" devarg for this device to specify the mode.
This patch let virtio pmd skip device probe when detecting this parameter.

vfio: add multi container support
This patch adds APIs to support container create/destroy and device
bind/unbind with a container. It also provides API for IOMMU programing
on a specified container.
A driver could use "rte_vfio_container_create" helper to create a new
container from eal, use "rte_vfio_container_group_bind" to bind a device
to the newly created container. During rte_vfio_setup_device the container
bound with the device will be used for IOMMU setup.

vfio: extend data structure for multi container
Currently eal vfio framework binds vfio group fd to the default
container fd during rte_vfio_setup_device, while in some cases,
e.g. vDPA (vhost data path acceleration), we want to put vfio group
to a separate container and program IOMMU via this container.
This patch extends the vfio_config structure to contain per-container
user_mem_maps and defines an array of vfio_config. The next patch will
base on this to add container API.
