As it causes issues when building with RTE_MACHINE=default due to SSE4.x
requirements and in other discussions was so far rated "lightly tested and
doesn't provide really significant performance improvement" let us disable
that in the default config.

Building RTE_LIBRTE_PMD_XENVIRT was broken when RTE_BUILD_COMBINE_LIBS was
enabled (http://dpdk.org/ml/archives/dev/2015-November/028660.html).
Now the underlying issue is rather simple, the xen code needs libxenstore.
But rte.app.mk so far only considered that when RTE_BUILD_COMBINE_LIBS was
disabled.
While it is correct to create the DPDK sublib linking only in the
RTE_BUILD_COMBINE_LIBS=n case, the libxenstore should be added to the linked
libs in any case if RTE_LIBRTE_PMD_XENVIRT is enabled.

We have encountered a CPU where the AES-NI instruction set is disabled
due to export restrictions. Since the build machine and target machine
is different, using -native configs doesn't work, and on this CPU, the
application refuses to run due to the AES CPU flags being amiss.
The patch passes EXTRA_CFLAGS to the figure-out-cpu-flags helper,
which allows us to add -mno-aes to the compile flags and resolve this

The initial problem has been seen while building mlx4 pmd as a shared
library on Ubuntu 14.04 (gcc 4.8.4-2ubuntu1~14.04).
Resulting .so will lack the DT_NEEDED entry for libibverbs:
marchand@ubuntu1404:~/dpdk$ ldd ./build/lib/librte_pmd_mlx4.so
linux-vdso.so.1 => (0x00007fff87ebb000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f2ced21a000)
/lib64/ld-linux-x86-64.so.2 (0x00007f2ced821000)
And trying to load it in testpmd triggers this error:
[...]
EAL: librte_pmd_mlx4.so: undefined symbol: ibv_query_port
[...]
After some strace, the problem comes from the --as-needed option passed to the
linker.
It is safer to specify libraries we depend on after the objects we are linking
into a shared library, especially when the linker is invoked with options like
--as-needed.

Signed-off-by: Chen Jing D(Mark) <jing.d.chen@intel.com>
Steps to reproduce the bug:
1. All Rx offloading is disabled and start the device, then
Vector Rx is used.
2. Stop the device. Re-configure to enable hw_ip_checksum = 1,
start the device again.
3. In this case, assume regular Rx should be used since Vector
Rx doesn't support ip checksum offload. But actually Vector
Rx is used and cause checksum won't be done by hardware.
The reason is after re-configuring, driver misses an "else" in
func fm10k_set_rx_function(). Then Rx func in last round are
used.

This patch provides the initial implementation of the AES-NI multi-buffer
based crypto poll mode driver using DPDK's new cryptodev framework.
This PMD is dependent on Intel's multibuffer library, see the whitepaper
"Fast Multi-buffer IPsec Implementations on Intel® Architecture
Processors", see ref 1 for details on the library's design and ref 2 to
download the library itself. This initial implementation is limited to
supporting the chained operations of "hash then cipher" or "cipher then
hash" for the following cipher and hash algorithms:
Cipher algorithms:
- RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)
Authentication algorithms:
- RTE_CRYPTO_AUTH_SHA1_HMAC
- RTE_CRYPTO_AUTH_SHA256_HMAC
- RTE_CRYPTO_AUTH_SHA512_HMAC
- RTE_CRYPTO_AUTH_AES_XCBC_MAC
Important Note:
Due to the fact that the multi-buffer library is designed for
accelerating IPsec crypto operation, the digest's generated for the HMAC
functions are truncated to lengths specified by IPsec RFC's, ie RFC2404
for using HMAC-SHA-1 with IPsec specifies that the digest is truncate
from 20 to 12 bytes.
Build instructions:
To build DPDK with the AESNI_MB_PMD the user is required to download
(ref 2) and compile the multi-buffer library on there system before
building DPDK. The environmental variable AESNI_MULTI_BUFFER_LIB_PATH
must be exported with the path where you extracted and built the multi
buffer library and finally set CONFIG_RTE_LIBRTE_PMD_AESNI_MB=y in
config/common_linuxapp.
Current status: It's doesn't support crypto operation
across chained mbufs, or cipher only or hash only operations.
