int is_new_node_eligible_for_ipv6	(	xcom_proto	incoming_proto,

	)

Checks if an incoming node is eligible to enter the group.

This function checks if a new node entering the group is able to be part of it. This is needed duw to downgrade procedures to server versions that do not speak IPv6. One wil check if:

Our server is being contacted by a server that has a lower version than the IPv6 baseline
Check if the current configuration is all reachable by an IPv4 node

If all of the above hold true we are able to proceed and add the node. Else, we must fail.

Return values

1	in case of success.
