Author: jhb Date: Thu Aug 30 17:47:39 2012 New Revision: 239913 URL: http://svn.freebsd.org/changeset/base/239913 Log: Attach interrupt handlers during attach instead of during the first time the interface is brought up. Without this, the boot time interrupt round-robin assignment does not think the allocated interrupt resources are active and leaves them assigned to CPU 0. While here, add descriptive tags to each interrupt handler when MSI-X is used.
