When writing to the mbuf array for receiving packets, do not assume
16-byte alignment by using aligned stores. If the pointers are only
8-byte aligned, the program will crash due to incorrect alignment.
Changing "store" to "storeu" fixes this.

This patch support mergeable RX feature and thus support jumbo frame RX and TX
in user space vhost(as virtio backend).
On RX, it secures enough room from vring to accommodate one complete scattered
packet which is received by PMD from physical port, and then copy data from
mbuf to vring buffer, possibly across a few vring entries and descriptors.
On TX, it gets a jumbo frame, possibly described by a few vring descriptors which
are chained together with the flags of 'NEXT', and then copy them into one scattered
packet and TX it to physical port through PMD.

non-optimised code path outperforms optimised one by 2-3%.

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

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.

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.
