'''Since we have not yet reworked the ACLs to rely on the pattern subsystem, it's still not possible to make use of "hdr_ip(X-f-f,-1)" as we do on the "balance" or "source" keywords.'''
Is the ACL rework mentioned for hddr_ip and a specific occurance (ie only the last one to avoid trivial spoofing) part of 1.5?
