New Revision: 325453
URL: https://svnweb.freebsd.org/changeset/base/325453
Log:
Fix an off-by-one error missed in the initial commit of this driver
When the segment count is > 16 it spills into an 'indirect descriptor list',
which immediately follows the main table, but the indirect list is entry 15,
so
needs to be skipped for the general list.
