examples/bond: add example application for link bonding mode 6
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).
