> I just realised that bitmap:ip,mac type of set (it is the only set which uses mac addresses) matches mac *only* on source and since ifb0 is only used on traffic coming in, then it is a mute point (I still have to test this though) - the above won't be needed, at least not for ip,mac address matching.

Does ipset even work on ifb interfaces? I thought those processed
traffic before it even hit iptables processing.  We do not yet use ipset
(very much want to but have not had the time to explore it) but we do
use ifb interfaces for traffic other than ingress shaping, e.g., when
applying the same shaping rules to multiple physical interfaces - John
