73d2c1d3f3 examples/ip_fragmentation: support big packets
In some vendors the RX and TX configuration must be the same, therefore
the MTU size need to be equal to max_rx_pkt_len.
The MTU is the largest size packet in bytes that can be sent on the
network, therefore before changing this parameter, the NIC could not
receive packets larger than 1500 bytes, which is the default MTU size.
In addition, scatter-gather need to be enabled in order to receive
frames bigger than mbuf size.

6ff7b996a8 examples/power: fix for p-state
The vm_power_manager starts by setting the environment to acpi
using rte_power_set_env(PM_ENV_ACPI_CPUFREQ). This causes a problem
starting vm_power_manager when the system is using the intel_pstate
driver. The env should be set to none, or not called at all, because
the library now auto-detects the environment to be either acpi or
intel_pstate. This patch sets the environment to none so that the
library can successfully auto-detect.

it is too excessive to use rte_memcpy() here,

29a62d1476 net/nfp: add CPP bridge as service
The Netronome's Network Flow Processor chip is highly programmable
with the goal of processing packets at high speed. Processing units
and other chip components are available from the host through the
PCIe CPP(Command Push Pull bus) interface. The NFP PF PMD configures
a CPP handler for setting up and working with vNICs, perform actions
like link up or down, or accessing extended stats from the MAC component.

There exist NFP host tools which access the NFP components for
programming and debugging but they require the CPP interface. When the
PMD is bound to the PF, the DPDK app owns the CPP interface, so these
host tools can not access the NFP through other means like NFP kernel
drivers.

This patch adds a CPP bridge using the rte_service API which can be
enabled by a DPDK app. Interestingly, DPDK clients like OVS will not
enable specific service cores, but this can be performed with a
secondary process specifically enabling this CPP bridge service and
therefore giving access to the NFP to those host tools.

This patch updates the translation routine for the E-Switch Flows.
Inner tunnel pattern items are translated into Netlink message,

We are going to support Flows matching with outer tunnel items
and not containing the explicit tunnel decap action (this one
might be drop, redirect or table jump, for exapmle).
So we can not rely on presence of tunnel decap action in the
list to decide whether the Flow is for tunnel, instead we will
use the presence of tunnel item. Item translation is rebound
to presence of tunnel items, instead of relying on decap action.

There is no way to tell kernel driver the outer address type
(IPv4 or IPv6) but specify the address flower key. The outer
address key is put on Netlink with zero mask if there is no
RTE item is specified in the list.

6b1a9b65be net/mlx5: remove checks for outer tunnel items on E-Switch
This patch removes unnecessary outer tunnel parameters check in the
validation routine for the E-Switch Flows. IPv4/IPv6 may have any
spec and mask, and transferred to tc without changes, all checks
are performed by kernel.

We are going to support Flows matching with outer tunnel items
and not containing the explicit tunnel decap action (this one
might be drop, redirect or table jump, for exapmle). So we can
not rely on presence of tunnel decap action in the list to decide
whether the Flow is for tunnel, instead we will use the presence
of tunnel item (like RTE_FLOW_ITEM_TYPE_VXLAN) in the item list.
The tunnel pattern checks within Flow validation routine are
rebound to presence of tunnel item. VXLAN decap action checks
for presence of VXLAN VNI item.

The tunnel UDP item is checked at the point of processing the tunnel
item (i.e. VXLAN). We can not perform UDP item check as tunnel once
UDP item encountered in the list, because it is not known yet whether
the tunnel item follows. The pointer to UDP item is saved and
checked as outer ones if tunnel item found.

cc28a6907b app/testpmd: fix pointer reference in macswap
The pointer is misused and could set wrong MAC address. As a result, some
of packets can be dropped in receiver side due to MAC address mismatch.
This can be shown as performance degradation.

04df418f0f net/tap: do not print pointer in info message
Printing pointer in log is uninformative (unless in a debugger),
instead print the assigned kernel device name which correlates
well with what TAP is doing.

c8ae56e62d net/tap: get rid of global name variable
Having a global variable which is set to "TUN" or "TAP" during
probe is a potential bug if probing is ever done in different
processes or contexts. Let's fix it now by using existing enum
that has type of connection.

b5235d61f3 net/tap: let kernel choose tun device name
Assigning tun and tap index in DPDK tap device driver is racy
and fails if used with primary/secondary. Instead use the kernel
feature of device wildcarding where if a name with %d is used
the kernel will fill in the next available device.

16f1c8abb5 net/tap: lower the priority of log messages
Any messages that normally occur during probe should be at DEBUG
level (not NOTICE). This reduces overall log clutter.
