Hi,

Why does broadcast work although I disabled it using the following:
ifconfig eth0 -broadcast

My goal is to disable dynamic arp address resolution. I want to configure
a firewall so that it only uses static arp addresses, that's why I need to
disable broadcast. I can't disable arp since the firewall needs to answer
arp requests for its own hardware address.

BTW, I also tried 'ifconfig broadcast 127.0.0.1' which is silly, but arp
still worked (checked with tcpdump) on that computer.
