New Revision: 249350
URL: http://svnweb.freebsd.org/changeset/base/249350
Log:
Update ciss(4) man page. We absolutely support performant mode of operation
on this controller. Indicate that the 5300 is the *only* controller that
will only work in simple mode.
Bus rescans should not be needed now and I consider it a bug if disks do
not appear or dissapear when created or destroyed.
