| Doc Text: |
Feature: Not blocking having several listeners (on different protocols) on the same port for ovn-octavia driver.
Reason: This was not supported previously on the ovn octavia driver, but now it is supported and there is no need to block it
Result: Several listeners on different protocols can be exposed in the same port. This means that we can have, for instance, the dns service to expose port 53 in both tcp and udp protocols when using ovn-octavia
