The tarball repository fast.dpdk.org is fast and reliable enough
to be used in VPP build process.

Check packet for presence of VLAN tag in the MAC header and set
the PKT_RX_VLAN_PKT flag to trigger sub-interface lookup in VPP
ethernet-input node.

* compiler -march= parameter is changed from native to corei7
so code is always genereted with instructions which are available
on the Nehalem microarchitecture (up to SSE4.2)
* compiler -mtune= parameter is added so code is optimized for
corei7-avx which equals to Sandy Bridge microarchitecture
* set of macros is added which allows run-time detection of available
cpu instructions (e.g. clib_cpu_supports_avx())
* set of macros is added which allows us to clone graph node funcitons
where cloned function is optmized for different microarchitecture
Those macros are using following attributes:
__attribute__((flatten))
__attribute__((target("arch=core-avx2)))
I.e. If applied to foo_node_fn() macro will generate cloned
functions foo_node_fn_avx2() and foo_node_fn_avx512() (future)
It will also generate function void * foo_node_fn_multiarch_select()
which detects available instruction set and returns pointer to the
best matching function clone.

VPP still needs to use packet type recognition in vRX path of the
ixgbe driver so ip packet can bypass ethernet-input node processing
for better performance. The shortcoming of packet type recognition
in the vRX path does not affect VPP.

DPDK 16.04 introduced new config parameter RTE_ARCH_X86
which was missing in the dpdk/Makefile
That caused issues with virtio devices on older kernels
(observed on 3.13.0).
This patch changes the source of generated config so
it will also include all defines in config/defconfig_TARGET
file.

This includes all patches in ENIC driver which are up-streamed to DPDK
to improve RX performance, fix buffer/error handling and interoperation
with link bonding PMD library.

poll mode driver library. The bonded interfaces to be created on
VPP startup is specified in the dpdk section of startup.conf
or qn.conf, using DPDK EAL command. Following is an example of a
dpdk section white listing PCI addressses of 4 ethernet interfacess
to be under VPP control plus two bonded interface and the PCI addresses
of the slaves in each:
dpdk { socket-mem 1024,1024
dev 0000:0f:00.0 dev 0000:10:00.0 dev 0000:11:00.0 dev 0000:12:00.0
vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34
vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34
}
Note that only balance XOR (mode 2) is supported and "xmit_policy=l34"
specifies to use layer 3 SIP/DIP and layer 4 Sport/Dport for load
balance. Using "xmit_policy=l2" for SMAC/DMAC or "xmit_policy=l23" for
SMAC/DMAC and SIP/DIP should also work.

Adding a patch to fix DPDK 2.2.0 enic PMD driver TX function.
The enic PMD driver send function uses a constant offset instead of relying on the data_off in the mbuf to find the start of the packet.
