doc: remove DPDK from guide titles

In HTML and PDF guides, it is clear in the header that the doc
is related to the DPDK.
So "DPDK" is redundant and can be removed from FAQ and release notes

examples/ip_pipeline: add sample configurations and scripts

This patch includes the configuration and script files of the some
applications which can be built using DPDK Packet Framework. A
configuration file defines the application structure which include
packet processing stages (knowns as pipelines), their connectivity
and other parameters necessary to start and run the application. A
script file specifies CLI commands required for loading table entries
(rules/routes, etc). The configuration/script files for simple
applications such as l2 forwarding, l3 forwarding have been presented.
In addition, to demonstrate the use and inter-connectivity of various
pipeline modules (which are avilable in packet framework), a complex
packet processing workload i.e. edge router is considered. The
configuration of the pipeline stages used for upstream and downstream
flow processing has been specified separately in two configuration
files. All these configuration and script files don't affect the
compilation.

bnx2x: update VF to support newer PF drivers

SR-IOV is supported using bnx2x poll mode driver running as VF driver and
native linux driver running as PF (in host/hypervisor). There is no issue
while running with the PF driver which is at the base version as that of
PMD. However, there is a compatibility issue between newer out-of-box PF
drivers with older VF driver. So the newer VFs would also need to send

cxgbe: fix Rx queue setup error management

When refilling freelists for the first time and if it fails, the rxq
is freed and returns ENOMEM. There is a check while freeing hardware rxq
to pass freelist context id if the freelist exists or 0xffff otherwise.
The error path is only reached if freelist exists. So, fix is to remove
the useless check for freelist existence.

app/testpmd: swap MAC in IEEE1588 forwarding

IEEE1588 forwarding mode uses same port to receive and transmit packets.
In this mode, the MAC address in the packets are not touched,
and therefore, packets could be sent with the same destination
MAC address as the MAC address of the port that is transmitting,
which causes the packet to be dropped in some NICs.

before packet is sent out.
