>Description:
We had some severe problems with router advertisements send by Quagga
[1]. It assumes that sizeof(struct sockaddr_dl.sdl_data) is 12
(interface name and MAC address). An interface name longer that 6
characters truncates the MAC address in the router advertisement. The
issue is known since 2007.

I wrote a patch and we tested it for several weeks.

>How-To-Repeat:
Create an interface with a name longer than 6 characters and verify the MAC address in the output of show interface in Quagga.
>Fix:
See https://bugzilla.quagga.net/show_bug.cgi?id=737.
