The skb->hash echo tag doesn't work here. isotp_set_skb_uid() is only called from the TX paths, never from isotp_send_fc(), so FC loopback echoes arrive with skb->hash == 0 and alias the so->cfecho == 0 "nothing pending" sentinel. Upstream is fine because d4fb6514ff8e stamps the UID in can_receive(), but that commit isn't on 6.18. -- Thanks, Sasha
