Yes, that would be nice. I wonder if that could lead to security problems on TX though. I guess It will only bring significant performance improvements if we leave the data writable in the user space or guest during the operation. If the user finds the right timing, it could modify the frame headers after they have been checked using netfilter, or while the frames are being consumed in the kernel (e.g. an NFS server running in a guest).
