e74a759a72 enic: migrate flow director filtering to new API
This patch helps enic migrate to the new flow-director API.

It takes care of the following.
1.  The change in fdir_filter structure and stats structure
2.  DPDK interface functions in enic_ethdev.c
3.  ENIC driver functions that deal with the VIC adapter

f12f13f2f6 use simple zero initializers
To initialize a structure with zeros, one field was explicitly set
to avoid "missing initializer" bug with old GCC (e.g. 4.4).
This warning is now disabled (commit <insertlater>) for old versions of GCC,
so the workarounds may be removed.

These initializers should not be needed for static variables but they
are still used to workaround an ICC bug (see commit b2595c4aa9).

There is one remaining exception where {0} initializer doesn't work cleanly,
even with recent GCC:
lib/librte_pmd_ixgbe/ixgbe_rxtx_vec.c:735:9:
error: missing braces around initializer [-Werror=missing-braces]
  struct rte_mbuf mb_def = {0}; /* zeroed mbuf */

Tested with gcc-4.4.7 (CentOS), gcc-4.7.2 (Debian), gcc-4.9.2 (Arch),
clang-3.6.0 and icc-13.1.1.

444b872a76 enic: fix possible data loss
Field ig_vlan_strip_en in struct enic type is int. It is used only by
function enic_set_nic_cfg which expects uint_8 as argument. Changed type
of the field to prevent possible loss of precision.

Macro GET_CONFIG passes result of sizeof operation to the function
vnic_dev_spec. This function expects parameter of type unsigned int.
Changed that parameter type to size_t in function declaration to prevent
possible data loss.

Define ENIC_ALIGN is used only by function rte_memzone_reserve_aligned,
which expects argument of type unsigned. Defined constant is of type
unsigned long long. Changed type to unsigned long to prevent possible
loss of precision.

In function writeq is written in two 32-bit long registers with writel
function. When trying to write val >> 32, static code analysis tool
reports that 64-bit value is passed to function expecting 32-bit value.
Added cast to clear this warning.

Issues found with static code analysis tool.

1f693b8f37 ethdev: remove useless parameter in init functions
The pointer to struct eth_driver is not used and is already set

133b75923b mk: add library version extension
To differentiate libraries that break ABI, we add a library version number
suffix to the library, which must be incremented when a given libraries ABI is
broken.  This patch enforces that addition, sets the initial abi soname
extension to 1 for each library and creates a symlink to the base SONAME so that
the test applications will link properly.

4e4510dfff ethdev: remove useless stats zeroing in drivers
The rte_eth_stats_get is the only API that should call the device
statistics function directly, and it already does a memset of the
resulting structure since commit 02331c16ec. Therefore doing
memset() in the driver is redundant and should be removed.

lib/librte_pmd_enic/enic_clsf.c:99:25: fatal error: missing field 'u' initializer [-Wmissing-field-initializers]

It fixes it by changing the initializer to set a named field to zero,
thereby automatically setting the rest of the unnamed fields also to
zero.

b70ae1899f enic: fix warnings
A lot of warnings were not seen because $(WERROR_FLAGS) was not set
in the Makefile. But they appear with toolchains that enforce more checks.

-Wno-deprecated seems useless.
-Wno-strict-aliasing is added to avoid false positives.

This patch cleans up unused variable, unused functions, wrong types,
static declarations, etc. A lot of functions have unused parameters;
it suggests that more clean-up could be needed.
