4f41de4fd5 i40e: support xen domain0
i40e was failing to run in XEN domain0, as the physical
memory for adminq DMA should be allocated and translated
in a different way for XEN domain0. So
rte_memzone_reserve_bounded() should be used for DMA
memory allocation, and rte_mem_phy2mch() should be used
for DMA memory address translation to support running
i40e PMD in XEN domain0.

7b4482e04b pcap: fix Rx crash
Normally, bufs[i] stores the mbuf pointer, the index of buf[i]
is the loop count i, but if header.len > buf_size, DPDK will
free the mbuf, but the loop count i still increases, so some
of the items in bufs[] might be NULL pointer, causing a potential
DPDK core. Using num_rx as the index for bufs[] solves the problem.

7e7ab81422 examples/l3fwd: improve grouping by destination port
Latest changes introduced a small degradation for the corner case
when each input packet is destined to the different port.
For the test-case when 1 core manages 4 ports and packet stream looks like:
IPV4_DSTPORT0, IPV4_DSTPORT1, IPV4_DSTPORT3, IPV4_DSTPORT4, IPV4_DSTPORT0, ...
non-optimised code path outperforms optimised one by 2-3%.
These changes supposed to close that gap.
From my testing: now for the case described above optimised code path
produces same numbers as non-optimised one.
For other test-cases numbers remain about the same.

a09b359dac kni: fix build on Ubuntu 14.04
Recent Ubuntu kernel 3.13.0-30.54, although based on Linux kernel 3.13.11,
already provides skb_set_hash() inline function, slightly different than
the one provided by lib/librte_eal/linuxapp/kni/ethtool/igb/kcompat.h

Ubuntu kernel 3.13.0-30.54 provides:
    * i40e/i40evf: i40e implementation for skb_set_hash
    - https://bugs.launchpad.net/bugs/1328037
    - http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_3.13.0-30.54/changelog

As a result, the implementation provided by kcompat.h must be skipped.
It is not appropriate to test whether LINUX_VERSION_CODE >= KERNEL_VERSION(3,13,11)
because previous Ubuntu kernel 3.13.0-29.53, already based on 3.13.11, needs to
get the implementation provided by kcompat.h

So the full Ubuntu kernel version numbering scheme must be tested:
<base kernel version>-<ABI number>.<upload number>-<flavour>
See "What does a specific Ubuntu kernel version number mean?"
and "How can we determine the version of the running kernel?"
at: https://wiki.ubuntu.com/Kernel/FAQ

Unlike RHEL_RELEASE_CODE, there is no such UBUNTU_RELEASE_CODE available out of
the box, so it needs to be crafted from the Makefile
Similarly, UBUNTU_KERNEL_CODE is generated with ABI and upload numbers.

`lsb_release -si` is first used to check whether we are running Ubuntu
`lsb_release -sr` provides release number 14.04, then converted to integer 1404
/proc/version_signature is parsed to get base kernel version, ABI and upload
numbers, and flavour is dropped

UBUNTU_KERNEL_CODE is indirectly defined using the UBUNTU_KERNEL_VERSION macro,
which in turn is defined in kcompat.h
This makes a single place to define the Ubuntu kernel version numbering scheme,
which is slightly different than the usual "shift by 8" scheme: ABI numbers can
be big (see: https://wiki.ubuntu.com/Kernel/Dev/TopicBranches), so 16-bits have
been reserved for them.

Finally, the implementaion of skb_set_hash is skipped in kcompat.h if we are
running Ubuntu 14.04 with an Ubuntu kernel >= 3.13.0-30.54

4094930e55 igb_uio: handle no IRQ fallback
Fix a couple of issues with my earlier igb_uio stuff:
1. With MSI (like MSI-X) actual IRQ number is not known until
   after the pci_enable_msi() is done.
2. If INTX fails, fall back to running without IRQ.
   This allows usermode PCI to recover and run without out IRQ
   for cases where PCI INTX support is broken (aka VMWare).

8d8d88cbd9 acl: make tailq fully local
Since the data structures such as rings are shared in their entirety,
those TAILQ pointers are shared as well. Meaning that, after a
successful rte_ring creation, the tailq_next pointer of the last
ring in the TAILQ will be updated with a pointer to a ring which may
not be present in the address space of another process (i.e. a ring
that may be host-local or guest-local, and not shared over IVSHMEM).
Any successive ring create/lookup on the other side of IVSHMEM will
result in trying to dereference an invalid pointer.

This patchset fixes this problem by creating a default tailq entry
that may be used by any data structure that chooses to use TAILQs.
This default TAILQ entry will consist of a tailq_next/tailq_prev
pointers, and an opaque pointer to arbitrary data. All TAILQ
pointers from data structures themselves will be removed and
replaced by those generic TAILQ entries, thus fixing the problem
of potentially exposing local address space to shared structures.

Technically, only rte_ring structure require modification, because
IVSHMEM is only using memzones (which aren't in TAILQs) and rings,
but for consistency's sake other TAILQ-based data structures were
adapted as well.

start address of the hugepages. Since the user would likely expect
the hugepages to be starting at the specified address, the specified

on page boundary) from the base virtual address and map the config

6258f1c942 eal: map shared config into exact same address as primary process
Shared config is shared across primary and secondary processes.
However,when using rte_malloc, the malloc elements keep references to
the heap inside themselves. This heap reference might not be referencing
a local heap because the heap reference points to the heap of whatever
process has allocated that malloc element. Therefore, there can be
situations when malloc elements in a given heap actually reference
different addresses for the same heap - depending on which process has
allocated the element. This can lead to segmentation faults when dealing
with malloc elements allocated on the same heap by different processes.

To fix this problem, heaps will now have the same addresses across
processes. In order to achieve that, a new field in a shared mem_config
(a structure that holds the heaps, and which is shared across processes)
was added to keep the address of where this config is mapped in the
primary process.

Secondary process will now map the config in two stages - first, it'll
map it into an arbitrary address and read the address the primary
process has allocated for the shared config. Then, the config is
unmapped and re-mapped using the address previously read.

So now there are three tests:

1 - Test two devices that share a ring, one device
    with just one RX queue and the other with one
    TX queue.

2 - Test a device connected to itself (loopback) by
    a ring, with both RX and TX queue.

3 - Test two devices that share a ring, but both devices
    with RX and TX queue, so they can send packets to themselves
    and to the other device.

403ac76b37 virtio: deinline some code
This driver has lots of functions marked always inline which is actually
counterproductive with modern compilers. Better to move the functions to
the one file they are used (proper scope) and let compiler decide.

For trivial functions leave them as static inline.

3ed4e9735a virtio: fix 32-bit build for 64-bit kernel
virtio_net_hdr_mem member within virtqueue structure stores a
physical address and is defined as void ptr. When 32bit pmd is used
with 64bit kernel this leads to truncation of 64bit physical address
and pkt i/o does not work.
Changed virtio_net_hdr_mem to phys_addr_t type and
removed the typecasts

484c308d3c igb_uio: fix build with kernel older than 3.3
Since Linux commit fb51ccbf217 (PCI: Rework config space blocking services),
the functions pci_(un)block_user_cfg_access are replaced by
pci_cfg_access_(un)lock.

The compatibility with older functions was broken since commit 399a3f0db8
(igb_uio: fix IRQ mode handling).

399a3f0db8 igb_uio: fix IRQ mode handling
This pach reworks how IRQ mode handling is done.

The biggest code change is to use the standard INTX management
code that exists in more recent kernels (and provide backport version).
This also fixes the pci_lock code which was broken, since it was
not protecting against config access, and was doing trylock.

Make this driver behave like other Linux drivers.
Start at MSI-X and degrade to less desireable modes
automatically if the desired type is not available.
