How to attach same XDP program to multiple interfaces

[byxzone]

I want to simultaneously attach the same XDP program to multiple InterFaces.
In libxdp, xdp_program__attach only can attach to one InterFace , if I use this function multi times, it will create multi Maps , but i want they use same Maps to interact with others
How can i do it ?

My scenario is like this: a machine loaded with XDP programs acts as a gateway, while attaching XDP programs on two (or more)InterFaces to complete SNAT/DNAT operations

This should be doable with libxdp (just attach the same xdp_prog multiple times), but there's no support for it in the xdp-loader cli. Not sure which you are after?
