Fedora 20 broadcast address

[Louis Lagendijk]

Some time ago I asked a question about the broadcast address on Fedora
20. On my desktop (installed from one of Alpha TC's) the interface is
brought up correctly, except that the broadcast address does not get set
correctly:
Ifconfig reports:

> p5p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
>         inet 192.168.159.186  netmask 255.255.255.0  broadcast 0.0.0.0

The broadcast address is not set when I use DHCP, but is also missing
when I use static address allocation. When I try a
ifdown p5p1; ifup05p1
the broadcast address is setup correctly.

Today I installed my laptop with Fedora 20 Beta. I see the same there:
The broadcast address is not set. I originally suspected a faulty nic
river. But on my laptop is occurs on both the wlan and ethernet
interfaces.

Does anybody else see the same thing? How can I debug this? With
NetworkManager I am quite clueless on how to tackle this.

Kind regards, Louis
