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

igb_uio: remove PCI id table

Removing PCI ID list to make igb_uio more similar to a generic driver
like vfio-pci or pci_uio_generic. This is done to make it easier for
the binding script to support multiple drivers.

Note that since igb_uio no longer has a PCI ID list, it can now be
bound to any device, not just those explicitly supported by DPDK. In
other words, it now behaves similar to PCI stub, VFIO and other generic
PCI drivers.

Therefore to bind a new device to igb_uio, the user will now have to
first write its PCI ID to "new_id" file inside the igb_uio driver
directory, and only then write the PCI ID to "bind". This is reflected
in changes to PCI binding script as well.

There's a weird behaviour of sysfs when a new device ID is added to
new_id. Subsequent writing to "bind" will result in IOError on
closing the file. This error is harmless but it triggers the
exception anyway, so in order to work around that, we check if the
device was actually bound to the driver before raising an error.

vfio: add multiprocess support

Since VFIO cannot be used to map the same device twice, secondary
processes receive the device/group fd's by means of communicating over a
local socket. Only group and container fd's should be sent, as device
fd's can be obtained via ioctl() calls' on the group fd.

For multiprocess, VFIO distinguishes between existing but unused groups
(e.g. grups that aren't bound to VFIO driver) and non-existing groups in
order to know if the secondary process requests a valid group, or if
secondary process requests something that doesn't exist.

VFIO multiprocess sync communicates over a simple protocol. It defines
two requests - request for group fd, and request for container fd.
Possible replies are: SOCKET_OK (an OK signal), SOCKET_ERR (error
signal) and SOCKET_NO_FD (a signal that indicates that the requested
VFIO group is valid, but no fd is present for that group - indicating
that the respective group is simply not bound to VFIO driver).

Here is the logic in a nutshell:

1. secondary process sends SOCKET_REQ_CONTAINER or SOCKET_REQ_GROUP
1a. in case of SOCKET_REQ_GROUP, client also then sends group number
2. primary process receives message
2a. in case of invalid group, SOCKET_ERR is sent back to secondary
2b. in case of unbound group, SOCKET_NO_FD is sent back to secondary
2c. in case of valid group, SOCKET_OK is sent and followed by fd
3. socket is closed

in case of any error, socket is closed and SOCKET_ERR is sent.

4. checks if the group is viable (that is, if all the devices in the

With latest HW and optimised RX/TX path there is a huge gap between
tespmd iofwd and l3fwd performance results.
So there is an attempt to optimise l3fwd LPM code path and reduce the gap:
 - Instead of processing each input packet up to completion -
 divide packet processing into several stages and perform
 stage by stage for the whole burst.
 - Unroll things by the factor of 4 whenever possible.
 - Use SSE instincts for some operations (bswap, replace MAC addresses, etc).
 - Avoid TX packet buffering whenever possible.
 - Move some checks from RX/TX into setup phase.

Note that new(optimized) code path can be switched on/off by setting
ENABLE_MULTI_BUFFER_OPTIMIZE macro to 1/0.
