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.

eal: add command line option to select vfio interrupt type
Unlike igb_uio, VFIO interrupt type is not set by kernel module
parameters but is set up via ioctl() calls at runtime. This warrants
a new EAL command-line parameter. It will have no effect if VFIO is
not compiled, but will set VFIO interrupt type to either "legacy", "msi"
or "msix" if VFIO support is compiled. Note that VFIO initialization
will fail if the interrupt type selected is not supported by the system.
If the interrupt type parameter wasn't specified, VFIO will try all
interrupt types (starting with MSI-X).

internal to Linuxapp EAL), so we check this flag regardless.

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.

vfio: DMA mapping
Adding code to support VFIO mapping (primary processes only). Most of
the things are done via ioctl() calls on either /dev/vfio/vfio (the
container) or a /dev/vfio/$GROUP_NR (IOMMU group).
In a nutshell, the code does the following:
1. creates a VFIO container (an entity that allows sharing IOMMU DMA
mappings between devices)
2. checks if a given PCI device is a member of an IOMMU group (if it's
not, this indicates that the device isn't bound to VFIO)
3. calls open() the group file to obtain a group fd
4. checks if the group is viable (that is, if all the devices in the
same IOMMU group are either bound to VFIO or not bound to anything)
5. adds the group to a container
6. sets up DMA mappings (only done once, mapping whole DPDK hugepage
memory for DMA, with a 1:1 correspondence of IOVA to PA)
7. gets the actual PCI device fd from the group fd (can fail, which
simply means that this particular device is not bound to VFIO)
8. maps BARs (MSI-X BAR cannot be mmaped, so skipping it)
9. sets up interrupt structures (but not enables them!)
10. enables PCI bus mastering

examples/l3fwd: reorganise and optimize LPM code path
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.
Some performance data:
SUT: dual-socket board IVB 2.8GHz, 2x1GB pages.
4 ports on 4 NICs (all at socket 0) connected to the traffic generator.
kernel: 3.11.3-201.fc19.x86_64, gcc: 4.8.2.
64B packets, using the packet flooding method.
All 4 ports are managed by one logical core:
Optimised scalar PMD RX/TX was used.
DIFF % (NEW-OLD)
IPV4-CONT-BURST: +23%
IPV6-CONT-BURST : +13%
IPV4/IPV6-CONT-BURST: +8%
IPV4-4STREAMSX8: +7%
IPV4-4STREAMSX1: -2%
Test cases description:
IPV4-CONT-BURST - IPV4 packets all packets from the one input port
are destined for the same output port.
IPV6-CONT-BURST - IPV6 packets all packets from the one input port
are destined for the same output port.
IPV4/IPV6-CONT-BURST - mix of the first 2 with interleave=1
(e.g: IPV4,IPV6,IPV4,IPV6, ...)
IPV4-4STREAMSX1 - 4 streams of IPV4 packets, where all packets

translates them into host space addresses, then attaches them to mbufs and puts the attached mbufs into

Queue starting and DMA refilling will get mbufs from mempool and use them to set the DMA addresses.
For TX, it gets the buffer addresses of available packets to be transmitted from guest and translates

However, if Linux PF has MTU > 1500, then DPDK VF receives no packets
(normal or jumbo).
With ixgbe_mbox_api_10 ixgbe simply didn't allow set VF MTU > 1514 for 82599.
With ixgbe_mbox_ajpi_11 it does, though now, if PF uses jumbo frames,
it simply disables RX for all VFs.
So to work with PF ithat using jumbo frames, at startup each VF has to:
1. negotiate with PF mbox_api_11.
2. Send to PF SET_LPE message with desired MTU.
Note, that if PF already uses MTU bigger then asked by the VF,
then PF wouldn't take any action.

timer: fix pending counter
Bug: When a timer is running
- if rte_timer_stop is called, the pending decrement is
skipped (decremented only if the timer is pending) and due
to the update flag the future processing is skipped so the
timer is counted as pending while it is stopped. - the same
applies when rte_timer_reset is called but then the pending
statistics is additionally incremented so the timer is
counted pending twice.
Solution: decrement the pending
statistics after returning from the callback. If
rte_timer_stop was called, it skipped decrementing the
pending statistics. If rte_time_reset was called, the
pending statistics was incremented. If neither was called
and the timer is periodic, the pending statistics is
incremented when it is reloaded

mk: fix linking drivers in static apps
The variable CONFIG_RTE_BUILD_SHARED_LIB was in rte.app.mk as

in the PMDs and just didn't work with any eth ports in any static builds.

sched: fix grinder bug
The rte_scheduler will get stuck and not deliver any more packets
if there are two active subports and then one of them stops enqueing
more packets. This is because of a bug in how the grinder state machines
are managed.
If a non-zero grinder is assigned (but not yet active), then the dequeue
would miss it and always return zero packets. The cure is to always
do a first pass over all grinders.

sched: use malloc instead of memzone for allocation
The existing rte scheduler can only be safely configured once per port
because a memory zone has a fixed size once it is created and can never
be freed or change in size.
This patch changes the scheduler to use rte_malloc instead. This allows
for a port to be reconfigured by doing rte_sched_port_free followed
rte_sched_port_config.
The patch also removes the now unused name parameter from the
port parameters structure.
