66ba596aa6 net/bnx2x: fix for PCI FLR after ungraceful exit
This patch provides a fix for PCI function level reset after an
ungraceful exit from an application. The fix is to enable internal
target read as part of device attach before getting device information
from device config space, device itself and shared memory. In addition
to that, add a 200ms delay for the recovery flow to complete.

972bf36106 ethdev: fix shallow copy of flow API RSS action
The rss_conf field is defined as a pointer to struct rte_eth_rss_conf.

Even assuming it is permanently allocated and a pointer copy is safe,
pointed data may change and not reflect an applied flow rule anymore.

This patch aligns with testpmd by making a deep copy instead.

d0ad8648b1 app/testpmd: fix RSS flow action configuration
Except for a list of queues, RSS configuration (hash key and fields) cannot
be specified from the flow command line and testpmd does not provide safe
defaults either.

In order to validate their implementation with testpmd, PMDs had to
interpret its NULL RSS configuration parameters somehow, however this has
never been valid to begin with.

This patch makes testpmd always provide default values.

The list of RSS types to use is exclusively taken from the global "rss_hf"
variable, itself configured through the "port config all rss" command or
--rss-ip/--rss-udp command-line options.

e153717a26 app/testpmd: fix lack of flow action configuration
Configuration structure is not optional with flow rule actions that expect
one; this pointer is not supposed to be NULL and PMDs should not have to
verify it.

Like pattern item spec/last/mask fields, it is currently set when at least
one configuration parameter is provided on the command line. This patch
sets it as soon as an action is created instead.

c77875fbb8 net/thunderx: fix MTU configuration for jumbo packets
thunderx pmd driver passes dev_info.max_rx_pktlen as
9200 (via rte_eth_dev_info_get()) to application.
But, when application tries to set MTU as
(9200 - sizeof(ethernet_header_t)) the operation fails
because of missing CRC and VLAN additions.

This patch fixes the following for thunderx pmd driver:
 - Sets NIC_HW_MAX_FRS to 9216 (instead of 9200)
 - Sets NIC_HW_MAX_MTU to 9190 (NIC_HW_MAX_FRS - ETH_HLEN
   - ETHER_CRC_LEN - 2*VLAN_HLEN)
 - Sets dev_info->max_rx_pkt_len to NIC_HW_MAX_MTU +
   ETH_HLEN (instead of 9200)
 - Allows rte_eth_dev_set_mtu() to pass if application
   (like VPP) calls rte_eth_dev_set_mtu() before
   rte_eth_dev_start() by putting appropriate check for
   dev->data->dev_started

93fb21fdbe net/enic: enable overlay offload for VXLAN and GENEVE
Recent NIC models support overlay offload. The overlay offload
feature enables the following on the NIC.
- 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
controls to individually enable tunnel types either. So do nothing for
now.

The driver enables overlay offload by default. Add a devargs
'disable-overlay=<0|1>' to allow the app to disable it.

Also update the enic guide doc.

a3f8150eac 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.

440f03c253 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.

ea2dc10668 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.

340b7bb8d5 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.

3701b792a8 bus/vdev: fix find device implementation
If start is set and a device before it matches the data,
this device is returned.

This induces potentially infinite loops.
