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.

eal/linux: fix Rx interrupt read error management

In eal_intr_proc_rxtx_intr, negative value may be used as argument to
a function expecting a positive value. If 'read' returns EAGAIN as
example, the bytes_read updates to a negative value which continue
be passed as argument for the next 'read'.

Coverity issue: 107115

Function read(fd, &buf, bytes_read) returns a negative number.
Assigning: signed variable bytes_read = read.
CID 107115 (#1 of 1): Argument cannot be negative
(NEGATIVE_RETURNS) bytes_read is passed to a parameter
that cannot be negative.
    bytes_read = read(fd, &buf, bytes_read);

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,
