Comment (by diver):
After issuing the following command:
{{{VBoxManage controlvm Haiku setlinkstate1 off}}}
this is what appears in syslog:
{{{
KERN: [net/pcnet/0] lost carrier
KERN: /dev/net/pcnet/0: media change, media 0x20 quality 1000 speed
1000000000
KERN: [net/pcnet/0] lost carrier
}}}
However, ifconfig still shows that the interface in question is UP:
{{{
/dev/net/pcnet/0
Hardware type: Ethernet, Address: 08:00:27:b8:ae:41
inet addr: 10.0.2.15, Bcast: 10.0.2.255, Mask: 255.255.255.0

Transmit: 7 packets, 0 errors, 954 bytes, 0 mcasts, 0 dropped

}}}
After a minute new stuff appears in the syslog:

pcnet is still UP:

{{{VBoxManage controlvm Haiku setlinkstate1 on}}}
doesn't print anything in th syslog
I decided to manually trigger auto-config
{{{ifconfig /dev/net/pcnet/0 auto-config}}}
