This patch fixes tx byte statistics when transmitting packets
with link down.
Previously, the counter would decrement 4 bytes for each packet that
was transmitted with link down, causing the uint64 to wrap around.

Similar to commit 113c8e13c4, but
for bnx2x, pcap, sze2data and xenvirt PMDs.
Requiring applications to know about library internal details like
dependencies to external helper libraries is a limitation of
static linkage, shared libraries should always know their own
dependencies for sane operation. This is especially highlighted
with dlopen()'ed items, having applications link against about plugin
internal dependencies goes on the side of absurd.
Note that linking with a shared combined library still requires to
know the internal dependencies.

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.

This patch adds a PMD for the Intel Quick Assist Technology DH895xxC

This patch depends on a QAT PF driver for device initialization. See

This patch supports a limited subset of QAT device functionality,
currently supporting chaining of cipher and hash operations for the
following algorithmsd:
Cipher algorithms:
- RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)
Hash algorithms:
- RTE_CRYPTO_AUTH_SHA1_HMAC
- RTE_CRYPTO_AUTH_SHA256_HMAC
- RTE_CRYPTO_AUTH_SHA512_HMAC
- RTE_CRYPTO_AUTH_AES_XCBC_MAC
Some limitation on this patchset which shall be contributed in a
subsequent release:
- Chained mbufs are not supported.
- Hash only is not supported.
- Cipher only is not supported.
- Only in-place is currently supported (destination address is
the same as source address).
- Only supports session-oriented API implementation (session-less

Most dpdk examples and apps seem to initialize with a minimum of 128 rx
descriptors and 512 tx descriptors for queue setup. However, CXGBE PMD
enforces a minimum of 1024 descriptors. This causes the dpdk stack
to return -EINVAL because the apps do not request the minimum required.
The fix is to relax this enforcing in CXGBE PMD. A minimum of 128
descriptors seems to be a good number with the least impact on the
performance.
