A stupid question is, can we manage to unify this ID with NAPI id?
Sorry I don't understand the question?
I mean can we associate page poll pointer to napi_struct, record NAPI id
in xdp_mem_info and do lookup through NAPI id?
No. The driver can unreg/reg a new XDP memory model,
Is there an actual use case for this?
without reloading
the NAPI and generate a new NAPI id.
We could still do this by e.g a allocator pointer protected by RCU I think?
Thanks
