Fix the handoff decision separately from the transmit result. An AI-generated review of v1 forwarded by Jakub identified a separate broadcast-mode leak: bc_transmit() returns without consuming the skb when no port is txable. Fix that in the second patch. v1: https://lore.kernel.org/r/20260926090039.1714460-1-bestswngs@gmail.com Changes since v1: - Use list_first_or_null_rcu() in the queue override helper, as Hangbin suggested, since only one override port can receive the skb. - Add a separate broadcast-mode fix for the no-port skb leak raised in the AI-generated review forwarded by Jakub.
