Split connection mark into two parts:
The lower nibble contains the confirmed conntrack mark which is not
generated by default/reclassify rules.
The upper nibble contains the current value specified by
default/reclassify rules.
For egress, the default/reclassify value is preferred
For ingress, the connection mark is preferred
