This is a Linux-specific virtual PMD driver backed by an AF_PACKET
socket. This implementation uses mmap'ed ring buffers to limit copying
and user/kernel transitions. The PACKET_FANOUT_HASH behavior of
AF_PACKET is used for frame reception. In the current implementation,
Tx and Rx queues are always paired, and therefore are always equal
in number -- changing this would be a Simple Matter Of Programming.
Interfaces of this type are created with a command line option like
"--vdev=eth_af_packet0,iface=...". There are a number of options available
as arguments:
- Interface is chosen by "iface" (required)
- Number of queue pairs set by "qpairs" (optional, default: 1)
- AF_PACKET MMAP block size set by "blocksz" (optional, default: 4096)
- AF_PACKET MMAP frame size set by "framesz" (optional, default: 2048)
- AF_PACKET MMAP frame count set by "framecnt" (optional, default: 512)

The mbuf structure already contains a pointer to the beginning of the

The Packet Framework pipeline library provides a standard methodology
(logically similar to OpenFlow) for rapid development of complex packet
processing pipelines out of ports, tables and actions.
A pipeline is constructed by connecting its input ports to its output ports
through a chain of lookup tables. As result of lookup operation into the
current table, one of the table entries (or the default table entry, in case
of lookup miss) is identified to provide the actions to be executed on the
current packet and the associated action meta-data.
The behavior of user actions is defined through the configurable table action
handler, while the reserved actions define the next hop for the current packet
(either another table, an output port or packet drop) and are handled
transparently by the framework.

This adds the code for a new Intel DPDK library for packet distribution.
The distributor is a component which is designed to pass packets
one-at-a-time to workers, with dynamic load balancing. Using the RSS
field in the mbuf as a tag, the distributor tracks what packet tag is
being processed by what worker and then ensures that no two packets with
the same tag are in-flight simultaneously. Once a tag is not in-flight,
then the next packet with that tag will be sent to the next available
core.

Poll Mode Driver for Paravirtual VMXNET3 NIC.
As a PMD, the VMXNET3 driver provides the packet reception and transmission
callbacks, vmxnet3_recv_pkts and vmxnet3_xmit_pkts. It does not support
scattered packet reception as part of vmxnet3_recv_pkts and
vmxnet3_xmit_pkts. Also, it does not support scattered packet reception as part of
the device operations supported.
The VMXNET3 PMD handles all the packet buffer memory allocation and resides in
guest address space and it is solely responsible to free that memory when not needed.
The packet buffers and features to be supported are made available to hypervisor via
VMXNET3 PCI configuration space BARs. During RX/TX, the packet buffers are
exchanged by their GPAs, and the hypervisor loads the buffers with packets in the RX
case and sends packets to vSwitch in the TX case.
The VMXNET3 PMD is compiled with vmxnet3 device headers. The interface is similar
to that of the other PMDs available in the Intel(R) DPDK API. The driver pre-allocates the
packet buffers and loads the command ring descriptors in advance. The hypervisor fills
those packet buffers on packet arrival and write completion ring descriptors, which are
eventually pulled by the PMD. After reception, the Intel(R) DPDK application frees the
descriptors and loads new packet buffers for the coming packets. The interrupts are
disabled and there is no notification required. This keeps performance up on the RX
side, even though the device provides a notification feature.
In the transmit routine, the Intel(R) DPDK application fills packet buffer pointers in the
descriptors of the command ring and notifies the hypervisor. In response the hypervisor
takes packets and passes them to the vSwitch. It writes into the completion descriptors
ring. The rings are read by the PMD in the next transmit routine call and the buffers
and descriptors are freed from memory.

These library changes provide a new Intel DPDK feature for communicating
with virtual machines using QEMU's IVSHMEM mechanism.
The feature works by providing a command line for QEMU to map several hugepages
into a single IVSHMEM device. For the guest to know what is inside any given IVSHMEM
device (and to distinguish between Intel(R) DPDK and non-Intel(R) DPDK IVSHMEM
devices), a metadata file is also mapped into the IVSHMEM segment. No work needs to
be done by the guest application to map IVSHMEM devices into memory; they are
automatically recognized by the Intel(R) DPDK Environment Abstraction Layer (EAL).
Changes in this patch:
* Changes to EAL to allow mapping of all hugepages in a memseg into a single file
* Changes to EAL to allow ivshmem devices to be transparently mapped in
the process running on the guest.
* New ivshmem library to create and manage metadata exported to guest VM's
* New ivshmem compilation targets
* Mempool and ring changes to allow export of structures to a VM and allow
a VM to attach to those structures.
* New autotests to unit tests this functionality.
