Each channel is opened in non-blocking mode, after a successful open a test

examples/vm_power: channel manager and monitor in host
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.

eal/linux: map pci memory resources after hugepages
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.

table: fix pointer calculations at initialization
During initialization of rte_table_hash_ext and rte_table_hash_lru, a
contiguous region of memory is allocated to store meta data, buckets,
extended buckets, keys, stack of keys, stack of extended buckets and
data entries. The size of each region depends on the hash table
configuration.
The address of each region is calculated using offsets relative to the
beginning of the memory region. Without this patch, the offsets
contain the size of the table meta data (sizeof(struct
rte_table_hash)). These addresses are stored in pointers which are
used when entries are added or deleted and lookups are performed.
Instead of adding these offsets to the address of the beginning of the
memory region, they are added to the address of the end of the meta
data (= address of the beginning of the memory region + sizeof(struct
rte_table_hash)). The resulting addresses are off by sizeof(struct
rte_table_hash) bytes. As a consequence, memory past the allocated
region can be accessed by the add, delete and lookup operations.
This patch corrects the address calculation by not including the size
of the meta data in the offsets.

vmxnet3: leverage data ring on Tx path
Data_ring is a pre-mapped guest ring buffer that vmxnet3
backend has access to directly without a need for buffer
address mapping and unmapping during packet transmission.
It is useful in reducing device emulation cost on the tx
path. There are some additional cost though on the guest
driver for packet copy and overall it's a win.
This patch leverages the data_ring for packets with a
length less than or equal to the data_ring entry size
(128B). For larger packet, we won't use the data_ring
as that requires one extra tx descriptor and it's not
clear if doing this will be beneficial.
Performance results show that this patch significantly

on the rx path:
(1) It adds unlikely hints on various infrequent error

(2) It also moves a constant assignment out of the pkt
polling loop. This saves one branching per packet.
Performance evaluation configs:
- On the DPDK-side, it's running some l3 forwarding app
inside a VM on ESXi with one core assigned for polling.
- On the client side, pktgen/dpdk is used to generate
64B tcp packets at line rate (14.8M PPS).
Performance results on a Nehalem box (4cores@2.8GHzx2)
shown below. CPU usage is collected factoring out the

2. Run and wait for the result

Usage Example:

set_rxtx_anchor [rxtx|rxonly|txonly]
