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.
