********* THIS OBJECT IS OBSOLETE ********* Indicates the position in a received frame which is to have the Wildcard Mask/Filter applied. The indicated packet byte is aligned with the 0th byte of the wildcard mask/filter held in network byte order. The MAC destination address starts at byte position (wildcardOffset) zero. The wildcardOffset must fall on a 2-byte boundary, 0,2,4,...,1512 (violations of this constraint result in a genErr). Filters can be aligned on non 2-byte boundaries through use of the wildcardUserOffset.
