Merged.
Best regards,

We are using the netfilter MARK in IPsec & QoS and this is causing conflicts.
Therefore, we use the highest bit in the IPS chain now and clear it afterwards because we do not really care about this after the packets have been passed through suricata.
Then, no other application has to worry about suricata.
