What you expected to happen
火焰图中包含应用span, 系统span和网络span，而通过tempo接口，只能查询到应用span和系统span, 网络span数据是缺失的。查看deepflow-app的源码，发现是有对网络span数据的处理的。

When adapting Tempo, in order to reduce the complexity of implementation, we did not support net span at the beginning. This feature will be completed in v6.3.
@duanshuaimin The net-span and sys-span currently share the same span ID, and there isn’t a good way to display them without modifying Tempo. We are still considering solutions and may need to recalculate the span IDs.
Additionally, we are considering another issue: in most cases, users only need to check the sys-span and app-span. If a network issue is suspected, they can directly search for the span ID in the request-log panel to identify which network hop is causing the problem. In other words, not displaying the net-span in Tempo might make the results simpler and more readable.
