From: Kishore Padmanabha <kishore.padmanabha@broadcom.com>

Added support for computed header fields in the result field
processing. The computed header fields are fields that are extracted
from header fields or derived from data that is not part of the flow
command but shall be used in setting up of the flow rule.
