That basically implies writing a small AF_FIELDBUS socket layer - it can do just demux then the kernel will do select/poll/receive and other grungy bits for you.

Demux is expected to be done the other side. So your socket layer rx would do
if(skb->len < MINLEN || ....) { kfree_skb(skb); return 0; }
sk=fieldbus_which_socket(skb); if(sk==NULL) { kfree... .. } skb->sk=sk; if(sock_queue_rcv_skb(sk, skb)<0) kfree_skb(skb); return 0;
or similar.
