is libxdp going to support kernel generic attach/detach/query API for multi-progs?

I am curious to know if libxdp is going to support the new merged generic attach/detach/query API for multi-progs, it is not using priority, if libxdp is going to support it, does it mean libxdp will also stop using program priority in the future?

Thanks

Yeah, we'll probably try to support that in some form, once it lands for XDP as well. Details TBD; my initial thought is that libxdp will keep using priorities to do its internal sorting when inserting new programmes, but use the kernel APIs to insert a program in the right place when adding/removing. We won't be able to support atomic replacement of multiple programs at once with the kernel mprog API, so not sure what to do about that...
