Hi,
      When we do a "dmesg" on a 4.2-STABLE box, we get:

arp: 200.42.126.18 moved from 00:e0:7d:7b:53:f0 to 00:c0:df:f4:ac:05 on ed0

and, in ifconfig, it says:

ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          inet 200.42.126.20 netmask 0xffffff00 broadcast 200.42.126.255
          inet6 fe80::2e0:7dff:fe7b:548a%ed0 prefixlen 64 scopeid 0x1
          ether 00:e0:7d:7b:54:8a

ed0 is connected to a switch. we want to know what the "arp: " message 
means. on the linux box, we have:

eth0      Link encap:Ethernet  HWaddr 00:C0:DF:F4:AC:05
           inet addr:200.42.126.18  Bcast:200.42.126.23  Mask:255.255.255.248
           UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
           RX packets:12738748 errors:0 dropped:0 overruns:0 frame:556

            Interrupt:10 Base address:0xe800
eth1      Link encap:Ethernet  HWaddr 00:E0:7D:7B:53:F0
            inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:3634104 errors:0 dropped:0 overruns:0 frame:4
            TX packets:3842298 errors:0 dropped:0 overruns:0 carrier:0
            collisions:197818 txqueuelen:100
            Interrupt:12 Base address:0xec00
  inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0

Both eth0 and eth1 are connected to that same switch.

Thank's.
