IB网卡名以ib开头时无法被识别，请问需要转换成Ethernet模式（名字以ens开头）才能被识别吗？请问为何这样设计？谢谢

src\common\net\Listener.cc
static bool checkNicType(std::string_view nic, Address::Type type) {
  switch (type) {
    case Address::TCP:
      return nic.starts_with("en") || nic.starts_with("eth") || nic.starts_with("bond");
    case Address::IPoIB:
      return nic.starts_with("ib");
    case Address::RDMA:
      return nic.starts_with("en") || nic.starts_with("eth") || nic.starts_with("bond");
    case Address::LOCAL:
      return nic.starts_with("lo");
    default:
      return false;
  }
}

The service that establishes an RDMA connection uses TCP, so at least one TCP NIC is required. The IB NIC does not necessarily have to operate in Ethernet mode.

请问当type为RDMA类型时，IB网卡名以ib开头时无法被识别，然后，改成IPoIB类型读写后通信有问题。请问如何解决？谢谢！
