This is a prerequisite to later support dynamic data types, e.g. string, as a set key. The string datatype (and integer) do not have a fixed size, instead the size is determined by the expression.
This keeps the expression all the way down to set construction. Furthermore, in case of concatenations we can use EXPR_CONCAT to allow the netlink linearization step to determine the original sizes of the keys components. Both changes are preparation work, they add no feature. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
