net/bnxt: fix Rx VLAN offload flags

The bnxt driver is not correctly setting the receive VLAN offload
flags.  When VLAN is offloaded the driver must set the
PKT_RX_VLAN_STRIPPED flag.

Actually, several drivers have the same bug, only most of the
Intel drivers look right. Any driver that sets vlan_tci is probably
stripping the tag, and should be setting RX_VLAN_STRIPPED.

To quote rte_mbuf.h:

/**
 * The RX packet is a 802.1q VLAN packet, and the tci has been
 * saved in in mbuf->vlan_tci.
 * If the flag PKT_RX_VLAN_STRIPPED is also present, the VLAN
 * header has been stripped from mbuf data, else it is still
 * present.

net/mlx5: support PCI device DMA map and unmap

The implementation reuses the external memory registration work done by
commit[1].

Note about representors:

The current representor design will not work
with those map and unmap functions. The reason is that for representors
we have multiple IB devices share the same PCI function, so mapping will
happen only on one of the representors and not all of them.

While it is possible to implement such support, the IB representor
design is going to be changed during DPDK19.05. The new design will have
a single IB device for all representors, hence sharing of a single
memory region between all representors will be possible.

bus: introduce device level DMA memory mapping

The DPDK APIs expose 3 different modes to work with memory used for DMA:

1. Use the DPDK owned memory (backed by the DPDK provided hugepages).
This memory is allocated by the DPDK libraries, included in the DPDK
memory system (memseg lists) and automatically DMA mapped by the DPDK
layers.

2. Use memory allocated by the user and register to the DPDK memory
systems. Upon registration of memory, the DPDK layers will DMA map it
to all needed devices. After registration, allocation of this memory
will be done with rte_*malloc APIs.

3. Use memory allocated by the user and not registered to the DPDK memory
system. This is for users who wants to have tight control on this
memory (e.g. avoid the rte_malloc header).
The user should create a memory, register it through rte_extmem_register
API, and call DMA map function in order to register such memory to
the different devices.

The scope of the patch focus on #3 above.

Currently the only way to map external memory is through VFIO
(rte_vfio_dma_map). While VFIO is common, there are other vendors
which use different ways to map memory (e.g. Mellanox and NXP).

The work in this patch moves the DMA mapping to vendor agnostic APIs.
Device level DMA map and unmap APIs were added. Implementation of those
APIs was done currently only for PCI devices.

For PCI bus devices, the pci driver can expose its own map and unmap
functions to be used for the mapping. In case the driver doesn't provide
any, the memory will be mapped, if possible, to IOMMU through VFIO APIs.

Application usage with those APIs is quite simple:
* allocate memory
* call rte_extmem_register on the memory chunk.
* take a device, and query its rte_device.
* call the device specific mapping function for this device.

Future work will deprecate the rte_vfio_dma_map and rte_vfio_dma_unmap
APIs, leaving the rte device APIs as the preferred option for the user.

vfio: skip DMA map failure if already mapped

Currently vfio DMA map function will fail in case the same memory
segment is mapped twice.

This is too strict, as this is not an error to map the same memory
twice.

Instead, use the kernel return value to detect such state and have the
DMA function to return as successful.

For type1 mapping the kernel driver returns EEXISTS.
For spapr mapping EBUSY is returned since kernel 4.10.

examples: detect default build directory

Most examples have in their makefiles a default RTE_TARGET directory to be
used in case RTE_TARGET is not set. Rather than just using a hard-coded
default, we can instead detect what the build directory is relative to

power: fix frequency list buffer validation

The frequency list buffer was already validated in
power_acpi_cpufreq_freqs(), so the newly added check was redundant.
To keep consistency with power_pstate_cpufreq_freqs(), remove the
original check and update the log message.

bus/dpaa: delay fman device list to bus probe

The fman device list need to be accessed across processes.
The hw device structures should be allocated with rte_calloc
instead of calloc. The rte_calloc is not available at the
time of bus scan, so better prepare the device list at probe.

bus/fslmc: remove unneeded strdup

The fslmc bus code was duplicating the device name and

When fslmc is built as part of a general distribution, the

This could confuse users it is not an error.

net/netvsc: fix VF support with secondary process

The VF device management in netvsc was using a pointer to the
rte_eth_devices. But the actual rte_eth_devices array is likely to
be place in the secondary process; which causes a crash.

The solution is to record the port of the VF (instead of a pointer)
and find the device in the per process array as needed.
