Currently, kernel pktgen has the feature to specify destination
address range for sending packet. (e.g. pgset "dst_min/dst_max")
But on samples, each pktgen script doesn't have any option to achieve this.
This commit adds the feature to specify the destination address range with CIDR.
-d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
# ./pktgen_sample01_simple.sh -6 -d fe80::20/126 -p 3000 -n 4
# tcpdump ip6 and udp
05:14:18.082285 IP6 fe80::99.71 > fe80::23.3000: UDP, length 16
05:14:18.082564 IP6 fe80::99.43 > fe80::23.3000: UDP, length 16
05:14:18.083366 IP6 fe80::99.107 > fe80::22.3000: UDP, length 16
05:14:18.083585 IP6 fe80::99.97 > fe80::21.3000: UDP, length 16

Currently, kernel pktgen has the feature to specify udp destination port
for sending packet. (e.g. pgset "udp_dst_min 9")
But on samples, each of the scripts doesn't have any option to achieve this.
This commit adds the DST_PORT option to specify the target port(s) in the script.
-p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed

Use "-f <num>", to specify the index of the first
sender thread.
In default first thread is #0.

Use -n <num>, to specify the number of packets every
thread sends.
Zero means indefinitely.

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:
