Fix Route for IPv6 default gateway

[tbe]

The IPv6 ressource checks the "destination" paramter for a ":" to decide if
the route is IPv4 or IPv6. If the destination is "default", it always assumes that
IPv4 is given, even it the gateway has a ":" in it.

The "gateway" parameter is more failsave for this, so we changed the logic to it.

Obviously the "default" case wasn't covered correctly. But what if the gateway is not specified (the route could also be via a device)? Could the user provide a name instead of an IP address for gateway? Would perhaps something like this be better: case "$OCF_RESKEY_destination $OCF_RESKEY_gateway" in *:*) addr_family="-6" ;; *) addr_family="-4" ;; esac

[tbe]

if names are a supported usecase, we would need an additional parameter like "addr_family".

If both, the destination and the gateway are names, we can not decide if the route is ipv4 or ipv6.

[dmuhamedagic]

Yes, obviously. However, you neither responded to other questions nor commented on the proposed alternative.

This wil fail if destination is an aliased network interface, eg 'ip route add default dev eth0:4'
