Igor Russkikh c8fd485202 samples: pktgen: new append mode
To configure various complex flows we for sure can create custom
pktgen init scripts, but sometimes thats not that easy.

New "-a" (append) option in all the existing sample scripts allows
to append more "devices" into pktgen threads.

The most straightforward usecases for that are:
- using multiple devices. We have to generate full linerate on
all physical functions (ports) of our multiport device.
- pushing multiple flows (with different packet options)

Daniel T. Lee f0681d95e7 samples: pktgen: add helper functions for IP(v4/v6) CIDR parsing
This commit adds CIDR parsing and IP validate helper function to parse
single IP or range of IP with CIDR. (e.g. 198.18.0.0/15)

Validating the address should be preceded prior to the parsing.
Helpers will be used in prior to set target address in samples/pktgen.

Daniel T. Lee 3cad8f9115 samples: pktgen: fix proc_cmd command result check logic
Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread',
'pg_set'. proc_cmd is designed to check command result with grep the
"Result:", but this might fail since this string is only shown in
'pg_thread' and 'pg_set'.

This commit fixes this logic by grep-ing the "Result:" string only when
the command is not for 'pg_ctrl'.

For clarity of an execution flow, 'errexit' flag has been set.

To cleanup pktgen on exit, trap has been added for EXIT signal.

Daniel T. Lee 226b96c25d samples: pktgen: add some helper functions for port parsing
This commit adds port parsing and port validate helper function to parse
single or range of port(s) from a given string. (e.g. 1234, 443-444)

Helpers will be used in prior to set target port(s) in samples/pktgen.

Jesper Dangaard Brouer b64b0d1e64 pktgen: new pktgen helper functions for samples scripts
Preparing for removing existing samples/pktgen/ scripts, and
replacing these with easier to use samples.

This commit provides two helper shell files, that can
be "included" by shell source'ing. Namely "functions.sh"
and "parameters.sh".

The parameters.sh file support easy and consistant parameter
parsing across the sample scripts.  Usage example is printed on
errors.

The functions.sh file provides, three new shell functions for
configuring the different components of pktgen: pg_ctrl(),
pg_thread() and pg_set().  A slightly improved version of the old
pgset() function is also provided for backwards compat.

The new functions correspond to pktgens different components.
 * pg_ctrl()   control "pgctrl" (/proc/net/pktgen/pgctrl)
 * pg_thread() control the kernel threads and binding to devices
 * pg_set()    control setup of individual devices

These changes are borrowed from:
