It may be better to remove this array and use BIT or << where
dgnc_offset_table is used instead.

If not, this should be const.

static const uint dgnc_offset_table[] = {
0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80
};

Hi, Joe.

Yes, I will remove this array, and use BIT or '<<' instead of using table.
But "a patch" as to have one meaning so I think this patch will be
sent with another one.
