mbuf: split mbuf across two cache lines.
This change splits the mbuf in two to move the pool and next pointers to
the second cache line. This frees up 16 bytes in first cache line.
The reason for this change is that we believe that there is no possible
way that we can ever fit all the fields we need to fit into a 64-byte
mbuf, and so we need to start looking at a 128-byte mbuf instead. Examples
of new fields that need to fit in, include -
* 32-bits more for filter information for support for the new filters in
the i40e driver (and possibly other future drivers)
* an additional 2-4 bytes for storing info on a second vlan tag to allow
drivers to support double Vlan/QinQ
* 4-bytes for storing a sequence number to enable out of order packet
processing and subsequent packet reordering
as well as potentially a number of other fields or splitting out fields
that are superimposed over each other right now, e.g. for the qos scheduler.
We also want to allow space for use by other non-Intel NIC drivers that may
be open-sourced to dpdk.org in the future too, where they support fields
and offloads that currently supported hardware doesn't.
If we accept the fact of a 2-cache-line mbuf, then the issue becomes
how to rework things so that we spread our fields over the two
cache lines while causing the lowest slow-down possible. The general
approach that we are looking to take is to focus the first cache
line on fields that are updated on RX , so that receive only deals
with one cache line. The second cache line can be used for application
data and information that will only be used on the TX leg. This would
allow us to work on the first cache line in RX as now, and have the
second cache line being prefetched in the background so that it is
available when necessary. Hardware prefetches should help us out
here. We also may move rarely used, or slow-path RX fields e.g. such
as those for chained mbufs with jumbo frames, to the second
cache line, depending upon the performance impact and bytes savings
achieved.

mbuf: add named points inside the structure
Add markers or "labels" at given points inside the mbuf which can be
used instead of individual fields to identify the start of logical

The use of typedefs and dummy fields was chosen over using unions
because of a couple reasons:
* unions cause an extra level of indentation (more likely two levels as
a union containing a struct for multiple fields would be needed). This
makes the lines longer than they need to be and increases the need for
wrapping. [This was the main reason]

mbuf: flatten struct vlan_macip
The vlan_macip structure combined a vlan tag id with l2 and l3 headers
lengths for tracking offloads. However, this structure was only used as
a unit by the e1000 and ixgbe drivers, not generally.
This patch removes the structure from the mbuf header and places the
fields into the mbuf structure directly at the required point, without
any net effect on the structure layout. This allows us to treat the vlan
tags and header length fields as separate for future mbuf changes. The
drivers which were written to use the combined structure still do so,
using a driver-local definition of it.
Reduce perf regression caused by splitting vlan_macip field. This is
done by providing a single uint16_t value to allow writing/clearing
the l2 and l3 lengths together. There is still a small perf hit to the
slow path TX due to the reads from vlan_tci and l2/l3 lengths being
separated. (<5% in my tests with testpmd with no extra params).
Unfortunately, this cannot be eliminated, without restoring the vlan
tags and l2/l3 lengths as a combined 32-bit field. This would prevent
us from ever looking to move those fields about and is an artificial tie
that applies only for performance in igb and ixgbe drivers. Therefore,
this patch keeps the vlan_tci field separate from the lengths as the
best solution going forward.

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

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.

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.

virtio: fix 32-bit build for 64-bit kernel
virtio_net_hdr_mem member within virtqueue structure stores a

with 64bit kernel this leads to truncation of 64bit physical address
and pkt i/o does not work.

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.

igb_uio: MSI-X cleanups
Since only one MSI-X entry is ever defined, there is no need to
put it as an array in the driver private data structure. One msix_entry
can just be put on the stack and initialized there.

I suspect this code was just inherited from some other project and
