The user may want to use only some bits of the skb mark in his skbedit rules because the remaining part might be used by something else. Introduce the "mask" parameter to the skbedit actor in order to implement such functionality. When the mask is specified, only those bits selected by the latter are altered really changed by the actor, while the rest is left untouched.
