efa8a43e39 cxgbe: fix build with icc
When compiling the cxgbe driver with icc, multiple errors about using
enums as integers appear across a number of files, including in the base
code and in the DPDK-specific driver code.

.../drivers/net/cxgbe/cxgbe_main.c(386): error #188: enumerated type mixed
with another type
                        t4_get_port_type_description(pi->port_type));
                                                     ^
For the errors in the base driver code we use the CFLAGS_BASE_DRIVER
approach used by other drivers to disable warnings.

For errors in the DPDK-specific code, typecasts are used to fix the
errors in the code itself.

6ffefc4c8f fm10k: support Xen domain0
fm10k was failing to run in XEN domain0, as the physical
memory for 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
fm10k PMD in XEN domain0.

b8bc1241d1 mlx4: shrink Tx queue elements for better performance
TX queue elements (struct txq_elt) contain WR and SGE structures required by
ibv_post_send(). This commit replaces them with a single pointer to the
related TX mbuf considering that:

- There is no need to keep these structures around forever since the
  hardware doesn't access them after ibv_post_send() and send_pending*()
  have returned.

- The TX queue index stored in the WR ID field is not used for completions
  anymore since they use a separate counter (elts_comp_cd).

- The WR structure itself was only useful for ibv_post_send(), it is
  currently only used to store the mbuf data address and an offset to the
  mbuf structure in the WR ID field. send_pending*() callbacks only require
  SGEs or buffer pointers.

Therefore for single segment mbufs, send_pending() or send_pending_inline()
can be used directly without involving SGEs. For scattered mbufs, SGEs are
allocated on the stack and passed to send_pending_sg_list().

58298a4e7b compat: add macro to map symbol in static build
It was pointed out in my examples that doing shared library symbol versioning by
partitioning symbols to version specific functions (as opposed to leaving the
latest symol version at the base symbol name), neglects to take into account
static builds.  Add a macro to handle that.  If you choose a versioning approach
that uniquely names every version of the symbol, then this macro lets you map
your symbol choice to the base name when building a static library

Also, while I'm at it, since we're documenting this in the guide, take the
abbreviated example out of the header

152143808d mk: fix static build on Fedora 22
On Fedora 22, the "ar" binary operates by default in deterministic mode,
making the "u" parameter irrelevant, and leading to warning messages
getting printed in the build output like below.

  INSTALL-LIB librte_kvargs.a
ar: `u' modifier ignored since `D' is the default (see `U')

There are two options to remove these warnings:
* add in the "U" flag to make "ar" non-deterministic again
* remove the "u" flag to have all objects always updated

This patch takes the second approach. It also explicitly adds in the "D"
flag to make behaviour consistent across different distributions which
may have different defaults.

c0362128c5 eal: fix pedantic build of mlx4 debug mode
Since the commit below includes rte_cpuflags.h in rte_spinlock.h,
compilation of the mlx4 driver fails when CONFIG_RTE_LIBRTE_MLX4_DEBUG=y.

This mode adds -pedantic to the compiler's command line for mlx4, which
complains about the static definition of an empty cpu_feature_table[] in
common rte_cpuflags.h, then about its redefinition as a larger array in
arch-specific rte_cpuflags.h.

While DPDK does not officially support -pedantic internally, external
applications may enable it and include rte_spinlock.h from the public API.

Instead of removing -pedantic from mlx4, this commit fixes rte_cpuflags.h.
