[dpdk-dev] [PATCH v2 4/6] bond: add example application for link bonding mode 6

[Michal Jastrzebski <michalx.k.jastrzebski@intel.com>]

v2 changes
- remove count parameter from send command
- fixed quit command to use cmdline_quit(cl)
- add echo function - all IPv4 packets will be retransmitted. Bonding
driver will use TLB policy - this will show how TX works in mode 6
- remove unused structures rx_conf_default and tx_conf_default
- add VLAN support
- remove unnecessary comments
- nodify show command in term of printing DEBUG informations

This patch contains an example for link bonding mode 6.
It interact with user by a command prompt. Available commands are:
Start - starts ARP_thread which respond to ARP_requests and sends
ARP_updates (this
Is enabled by default after startup),
Stop  -stops ARP_thread,
Send count ip - send count ARP requests for IP,
Show - prints basic bond information, like IPv4 statistics from clients
Help,
Quit.
The best way to test mode 6 is to use this example together with
previous patch:
[PATCH 3/4] bond: add debug info for mode 6 link bonding.
Connect clients thru switch to bonding machine and send:
arping -c 1 bond_ip or
generate IPv4 traffic to bond_ip (IPv4 traffic from different clients
should be then balanced on slaves in round robin manner).
