Correctly setup from..to variables where no IPSET_ATTR_IP_TO{,2} attribute is given, so in range processing loop we construct proper cidr value. Check whenever we have no ranges and can short cut in hash:net,net properly. Use unlikely() where appropriate, to comply with other modules. Signed-off-by:
