Subject: [PATCH] net:ipv4: Packet is not forwarded when ingress interface is not configured with bc_forwarding

Allow an IPv4 packet with a destination address of broadcast to be forwarded 
if the ingress interface is not configured with bc_forwarding but the egress 
interface is. This is inline with Cisco's implementation of directed 
broadcast.

    configured with bc_forwarding
