Steps to reproduce:
1) Start capturing packets
2) Do "sudo ifconfig eth0 down" (or alternatively "sudo /etc/init.d/networking
restart")
3) Wireshark stops capturing and displays this messagebox:
"Error while capturing packets: recvfrom: Network is down
Please report this to the Wireshark developers. (This is not a crash;
please do not report it as such.)"
Expected behavior:
Wireshark will continue capturing packets that arrive while the interface does
not have IPv4 address.
Motivation: Allow debugging DHCP client problems.
