[PATCH net] ipv4: not do cache for local delivery if bc_forwarding is enabled

2019-06-02 Thread Xin Long
With the topo: h1 ---| rp1| | route rp3 |--- h3 (192.168.200.1) h2 ---| rp2| If rp1 bc_forwarding is set while rp2 bc_forwarding is not, after doing "ping 192.168.200.255" on h1, then ping 192.168.200.255 on h2, and the packets can still be forwared.
