[NEW PORT] net/fping+ipv6: Quickly ping N hosts w/o flooding the network - IPv6 version

This is an IPv6 only version of fping. The fping with IPv6 patch cannot handle
	IPv4 ping, therefore I think it is better to have two distinct port:
	fping - IPv4 only
	fping+ipv6 - IPv6 only

	Maintainer of fping also copied. He can maintain both port if he agrees.
	-------------------------------------------------

	A tool to quickly ping N number of hosts to determine their reachability
	without flooding the network.

	fping is different from ping in that you can specify any number of
	hosts on the command line, or specify a file containing the lists
	of hosts to ping. Instead of trying one host until it timeouts or
	replies, fping will send out a ping packet and move on to the next
	host in a round-robin fashion. If a host replies, it is noted and
	removed from the list of hosts to check. If a host does not respond
	within a certain time limit and/or retry limit it will be considered
	unreachable.

	Unlike ping, fping is meant to be used in scripts and its
	output is easy to parse.
	This is an IPv6 only version.
