NIC resource may fault during group offline or failover on Solaris 11

When NIC resource is configured with exclusive IP zone, NIC resource may fault during group offline or failover. This issue is observed as zone takes long time in shutdown on Solaris 11. If NIC monitor is invoked during this window, NIC agent may treat this as fault.

Workaround: Increase ToleranceLimit for NIC resource when it is configured for exclusive IP zone.
