Hi Team,

Could you help me out with Listener configurations in kafka resource configurations. I am struggling with external listener configurations as i am using metallb. Is there any configuration changes required for metallb.
kafka-persistent.yaml:

apiVersion: kafka.strimzi.io/v1beta1

kind: Kafka
