The currnent implementation sets a gre mask with protocol masked in case the user did not supply the protocol mask. In template mode, for group 0, the gre translation was called once with the mask and later with the value. with gre open matcher(mask/value is null) default values were assigned gre protocol mask=0xffff and gre protocol value=0. Therefore gre packet with protocol value not equal zero, will not match the rule. Changed the default protocol mask to be zero instead of 0xffff. In case of empty gre match, this fix will ignore the protocol field matching, gre will only be matched by the IP next header field in previous header in packet.
