ipv6 plugin crashes when IP address has link local interface

[avibrazil]

Apache logs link-local IPv6 addresses appending its local network interface. Like this:

fe80::5748:b385:9b31:5fd%br0

This crashes completely ipv6 plugin. This HTTP request came from a host in my LAN which IP address is fe80::5748:b385:9b31:5fd and it connected in the server's br0 interface.

For now I'm cleaning my logs, but I think the plugin should handle these IPv6 address representation ignoring everything after the %. Or, even better, considereing the interface too... maybe someone wants to track in reports the interface the connections came from.

Thank you in advance
