Hi List,

I am looking at if_ether.c on current 6.2 and it looks to me like
net.link.ether.inet.proxyall has to be set to 1 for proxy arp to
work. Am I reading this correctly? If so this is misleading based on
the description of this sysctl in man 4 arp.

Also is anybody using proxy arp?

Thanks,
Steve
