b974e4a40c ethdev: make error checking macros public
Move the function pointer and port id checking macros to rte_ethdev and
rte_dev header files, so that they can be used in the static inline
functions there. Also replace the RTE_LOG call within
RTE_PMD_DEBUG_TRACE so this macro can be built with the -pedantic flag

badb3688ff eal/linux: fix build with glibc < 2.12
pthread_setname_np() function added in glibc 2.12, using this function
in older glibc versions cause compile error:
error: implicit declaration of function "pthread_setname_np"

This patch adds "rte_thread_setname" macro and set it according
glibc >= 2.12 check, thread naming disabled for older glibc versions,
glibc versions that support "pthread_setname_np" will keep using this
function.

b0fb5155f8 kni: use utsrelease to determine Ubuntu kernel version
/proc/version_signature is the version for the host machine, but in
e.g., chroots, this does not necessarily match that DPDK is built
for. DPDK will then build for the wrong kernel version - that of the
server, and not that installed in the (build) chroot.

The patch uses utsrelease.h from the kernel sources instead and fakes
the upload version.

Tested on a server with Ubuntu 12.04, building in a chroot for Ubuntu
14.04.

Someone may need to call rte_eal_init() with a fake argc/argv array
in the middle of using getopt() to parse its own unrelated argc/argv
parameters. So getopt lib shouldn't be reset by rte_eal_init().

Now eal will always save optind, optarg and optopt (and optreset on
FreeBSD) at the beginning, initialize optind (and optreset on FreeBSD)
to 1 before calling getopt_long(), then restore all values after.

b13bfab4cd eal: reserve VFIO vector zero for misc interrupt
During VFIO_DEVICE_SET_IRQS, the previous order is
{Q0_fd, ... Qn_fd, misc_fd}.
The vector number of misc is indeterminable which is
ugly to some NIC (e.g. i40e, fm10k).
The patch adjusts the order in {misc_fd, Q0_fd, ... Qn_fd},
always reserve the first vector to misc interrupt.

Kernel 4.2 has introduced two new parameters in ndo_bridge_getlink,
which breaks DPDK compilation.

This patch adds the necessary checks to fix it.

492d31ac02 kni: rename macro for igb nlflags
Rename HAVE_NDO_BRIDGE_GETLINK_FILTER_MASK macro for
a more meaningful HAVE_NDO_BRIDGE_GETLINK_NLFLAGS,
as the macro is used to know if igb_ndo_bridge_getlink
function has nlflags parameter.

72a7a2b246 kni: allow per-net instances
There is a global variable 'device_in_use' which is used to make sure
only one instance is using /dev/kni device. If you were using LXC, you
will find there is only one instance of KNI example could be run even
different namespaces were created.

In order to have /dev/kni used simultaneously in different namespaces,
making all of global variables as per network namespace variables.

With regard to single kernel thread mode, there will be one kernel
thread for each of network namespace.

9e21671599 eal: add option to delete hugepage backing files
When an application using huge-pages crash or exists, the hugetlbfs
backing files are not cleaned up. This is a patch to clean those files.
There are multi-process DPDK applications that may be benefited by those
backing files. Therefore, I have made that configurable so that the
application that does not need those backing files can remove them, thus
not changing the current default behavior. The application itself can
clean it up, however the rationale behind DPDK cleaning it up is, DPDK
created it and therefore, it is better it unlinks it.
