To support the meter policy for yellow action, the prerequisite is
that the hardware needs to support the EBS and then the yellow color
of packets can be marked for the further steering.
In the current implementation EBS and overflow were ignored when
creating a meter profile. With this commit, if EBS is set by the
application, the generation of yellow color will be enabled in the
hardware for flow rules steering of packets.
