ifconfig and arp

[Frank de Bot <netbsd%searchy.net@localhost>]

Hi,

When I tried to enable/disable the ARP resolution protocol on an 
interface, I encounterd something strange. As documentation described 
'-arp' should disable it, and 'arp' enable it.

I entered the following commands:
-bash-3.2# ifconfig wm1 arp
-bash-3.2# ifconfig wm1 | grep flag
wm1: 
flags=8bc3<UP,BROADCAST,RUNNING,NOARP,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> 
mtu 1500
-bash-3.2# ifconfig wm1 -arp
-bash-3.2# ifconfig wm1 | grep flag
wm1: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> 
mtu 1500

But it seems 'arp' DISABLED ARP resolution protocol and 'arp' enabled it 
again. Is it a bug in documentation or in 'ifconfig'?

I use NetBSD 5.0rc2
