Moved the current librte_power implementation to rte_power_acpi_cpufreq, with
renaming of functions only.
Added rte_power_kvm_vm implementation to support Power Management from a VM.
librte_power now hides the implementation based on the environment used.
A new call rte_power_set_env() can explicidly set the environment, if not
called then auto-detection takes place.
rte_power_kvm_vm is subset of the librte_power APIs, the following is supported:
rte_power_init(unsigned lcore_id)
rte_power_exit(unsigned lcore_id)
rte_power_freq_up(unsigned lcore_id)
rte_power_freq_down(unsigned lcore_id)
rte_power_freq_min(unsigned lcore_id)
rte_power_freq_max(unsigned lcore_id)
The other unsupported APIs return -ENOTSUP

Allows for the opening of Virtio-Serial devices on a VM, where a DPDK
application can send packets to the host based monitor. The packet formatted is
specified in channel_commands.h
Each device appears as a serial device in path
/dev/virtio-ports/virtio.serial.port.<agent_type>.<lcore_num> where each lcore
in a DPDK application has exclusive to a device/channel.
Each channel is opened in non-blocking mode, after a successful open a test
packet is send to the host to ensure the host side is monitoring.

Provides a small sample application(guest_vm_power_mgr) to run on a VM.
The application is run by providing a core mask(-c) and number of memory
channels(-n). The core mask corresponds to the number of lcore channels to
attempt to open. A maximum of 64 channels per VM is allowed. The channels must
be monitored by the host.
After successful initialisation a CPU frequency command can be sent to the host
using:
set_cpu_freq <lcore_num> <up|down|min|max>.

The CLI is used for administrating the channel monitor and manager and
manually setting the CPU frequency on the host.
Supports the following commands:
add_vm [Mul-choice STRING]: add_vm|rm_vm <name>, add a VM for subsequent
operations with the CLI or remove a previously added VM from the VM Power
Manager
rm_vm [Mul-choice STRING]: add_vm|rm_vm <name>, add a VM for subsequent
operations with the CLI or remove a previously added VM from the VM Power
Manager
add_channels [Fixed STRING]: add_channels <vm_name> <list>|all, add
communication channels for the specified VM, the virtio channels must be
enabled in the VM configuration(qemu/libvirt) and the associated VM must be
active. <list> is a comma-separated list of channel numbers to add, using the
keyword 'all' will attempt to add all channels for the VM
set_channel_status [Fixed STRING]:
set_channel_status <vm_name> <list>|all enabled|disabled, enable or disable
the communication channels in list(comma-separated) for the specified VM,
alternatively list can be replaced with keyword 'all'. Disabled channels will
still receive packets on the host, however the commands they specify will be
ignored. Set status to 'enabled' to begin processing requests again.
show_vm [Fixed STRING]: show_vm <vm_name>, prints the information on the
specified VM(s), the information lists the number of vCPUS, the pinning to
pCPU(s) as a bit mask, along with any communication channels associated with
each VM
show_cpu_freq_mask [Fixed STRING]: show_cpu_freq_mask <mask>, Get the current
frequency for each core specified in the mask
set_cpu_freq_mask [Fixed STRING]: set_cpu_freq <core_mask> <up|down|min|max>,
Set the current frequency for the cores specified in <core_mask> by scaling
each up/down/min/max.
show_cpu_freq [Fixed STRING]: Get the current frequency for the specified core
set_cpu_freq [Fixed STRING]: set_cpu_freq <core_num> <up|down|min|max>,

The manager is responsible for adding communications channels to the Monitor
thread, tracking and reporting VM state and employs the libvirt API for
synchronization with the KVM Hypervisor. The manager interacts with the
Hypervisor to discover the mapping of virtual CPUS(vCPUs) to the host
physical CPUS(pCPUs) and to inspect the VM running state.
The manager provides the following functionality to the CLI:
1) Connect to a libvirtd instance, default: qemu:///system
2) Add a VM to an internal list, each VM is identified by a "name" which must
correspond a valid libvirt Domain Name.
3) Add communication channels associated with a VM to the epoll based Monitor
thread.
The channels must exist and be in the form of:
/tmp/powermonitor/<vm_name>.<channel_number>. Each channel is a
Virtio-Serial endpoint configured as an AF_UNIX file socket and opened in
non-blocking mode.
Each VM can have a maximum of 64 channels associated with it.
4) Disable or re-enable VM communication channels, channels once added to the
Monitor thread remain in that threads control, however acting on channel
requests can be disabled and renabled via CLI.
The monitor is an epoll based infinite loop running in a separate thread that
waits on channel events from VMs and calls the corresponding functions. Channel
definitions from the manager are registered via the epoll event opaque pointer
when calling epoll_ctl(EPOLL_CTL_ADD), this allows for obtaining the channels
file descriptor for reading EPOLLIN events and mapping the vCPU to pCPU(s)
associated with a request from a particular VM.

This is a very simple example app for doing packet forwarding with the
Intel DPDK. It's designed to serve as a start point for people new to
the Intel DPDK and who want to develop a new app.
Therefore it's meant to:
* have as good a performance out-of-the-box as possible, using the
best-known settings for configuring the PMDs, so that any new apps can
be based off it.
* be kept as short as possible to make it easy to understand it and get
started with it.

Multi-process DPDK application must mmap hugepages and PCI resources
into the same virtual address space. By default the virtual addresses
are chosen by the primary process automatically when calling the mmap.
But sometimes the chosen virtual addresses aren't usable in secondary
process - for example, secondary process is linked with more libraries
than primary process, and the library occupies the same address space
that the primary process has requested for PCI mappings.
This patch makes EAL try and map PCI BARs right after the hugepages
(instead of location chosen by mmap) in virtual memory, so that PCI BARs
have less chance of ending up in random places in virtual memory.

support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
- To 'struct rte_eth_rss_reta_entry64' which contains 64
entries and 64 bits mask.
- Array of above new structure can be used for any number of
redirection table entries, as long as the number is multiple
of 64. This is quite flexible for the future expanding of
redirection table.
* Redefinition of relevant interfaces in ethdev.
- Interface of reta update has been redefined with new parameters.
- Interface of reta query has been redefined with new parameters.
* Rework of 1G PMD in igb.
