请问如何新增 gateway 的监听端口 || How to add the listening port of gateway

[lhlxc]

集群入口为 ingress-nginx，请求都是由 ingress-nginx 转发到 higress 的 80 端口。请求包括 gRPC （http 2.0）和 http（http 1.x），ingress-nginx 对于上游 higress 的 80 端口共用一个连接池，造成 http 2.0 和 http 1.x 连接混用，导致请求错误。相似情况可以参考https://github.com/kubernetes/ingress-nginx/issues/4836，目前希望 higress 能够再开一个端口，专门用于转发 gRPC 请求，实现和 http 请求的区分。但没有找到新增端口的文档，只有修改端口号的文档，请问能否实现？

The cluster entrance is ingress-nginx, and requests are forwarded by ingress-nginx to port 80 of higress. Requests include gRPC (http 2.0) and http (http 1.x). Ingress-nginx shares a connection pool for port 80 of the upstream higress, causing http 2.0 and http 1.x connections to be mixed, resulting in request errors. For similar situations, please refer to kubernetes/ingress-nginx#4836. Currently, we hope that higress can open another port specifically for forwarding gRPC requests to distinguish it from http requests. But I couldn't find the documentation for adding a new port, only the documentation for modifying the port number. Can this be achieved?
